Cobra Show

The London Cobra Show – June 22, 23 and 24, 2017


Dr. Dan Semko, DPM

Dan is one of four friends that came up with the idea of combining their love of Cobras and picnicking and turned the idea into what they called the Double Venom Spring Fling, which became known as DVSF. Their DVSF formed the basis of what today is the London Cobra Show.

Dan was born in Youngstown, Ohio and later raised in Cleveland Heights, Ohio where he graduated from Cleveland Heights High School in 1967. Dan enlisted in Navy as a Fleet Marine Force Hospital Corpsman and was assigned to the 3rd and 9th Marine Divisions where he completed 2 tours as a front line Corpsman in Northern Vietnam.

Upon discharge from the Navy, Dan became an Orthopedic Physician’s Assistant in Lorain, Ohio and later in Milwaukee, Wisconsin while he completed his pre-medical requirements at Marquette University. Dan graduated from The Ohio College of Podiatric Medicine in 1980 and established his medical practice in Richmond, Indiana with his best friend Sue Haritatos, who is also a doctor and, in 1983 became his wife. The couple has resided in Richmond, Indiana for 37 years.

Dan has been an avid cobraphile starting with his first Superformance #760, purchased from Dynamic Motorsports in Ross, Ohio and ending with an aluminum bodied Shelby Continuation Cobra - CSX #4148 originating from Shelby American. During his cobra life Dan has met some of the nicest type A personalities and has enjoyed friendships with cobraphiles from all over the entire world.

  • Roadster with a 289 ci engine
  • King Cobra
  • Daytona Coupe
  • King Cobra-Lang Cooper

While Dave's racing career was short, lasting less than five years, his impact on American racing history is significant, as he competed in a total of 101 races with 44 victories and 65 top 3 finishes.

Dave was just 27 years old when he lost his life in the 1964 Indianapolis 500. He was respected among his peers for his remarkable driving ability and by all who knew him for his dedication to his family.

Mr. John Morton

Vintage Race Car Driver and Author

John’s interest in racing was sparked as a child by attending local dirt track races with his dad at the Waukegan Speedway in his Illinois hometown. While in college John began his racing career on a dirt track near Clemson.

In 1962 John traveled to California to attend Carroll Shelby's School of High Performance Driving, a five-day course with Peter Brock as John’s instructor. John was then able to obtain a job, with Shelby American Racing, not as a race car driver but at the end of a broom handle. Later, John was promoted to making oil pans for Shelby, earning $3.25 per hour. Finally, John got the chance he wanted at Shelby American Racing and drove a 427 Cobra at Sebring International Raceway.

In 1968, Peter Brock asked John to join his new BRE Datsun racing team. After his time with BRE, John went on to race a few years in F5000, Can-Am and various IMSA races. John's racing victories include an overall victory at Sebring and several class wins, including the 24 Hours of Le Mans in 1994. John has competed at Le Mans a total of nine times.

Inside Shelby American, Wrenching and Racing with Carroll Shelby in the 1960s is the title of a book, John has written. The book is about his working for Carroll Shelby and he will be selling signed copies of his book on Friday and Saturday.

What began as the Double Venom Spring Fling and later became the London Cobra Show, had its beginning shortly before Christmas of 1999. It all began when four Cobra loving friends, Gary Osborne, Dan and Dave Semko, got together with Ed Combs, at Ed's house near Columbus, Ohio. The reason for the meeting was for a pre-holiday celebration. At the time, Ed's wife just happened to serve the group some of her chocolate chip cookies. Later, one of the men would state on the Club Cobra forum that - “Ed's wife made the best chocolate chip cookies in the world.” As you can imagine, that comment led others on Club Cobra to say that their wife was the best cook.

Eventually, the comments on Club Cobra led to a suggestion for a Cobra family picnic during the spring of 2000. It was decided that the picnic would allow everyone the opportunity for a cook-off, to see who actually did cook the best tasting food. From that small picnic of 20 or so people, it became a full-fledged international Cobra Event called the Double Venom Spring Fling or simple DVSF in 2001. The name came about, due to the fact that Ed Combs owned a Viper V-10-powered Cobra.

As the event was becoming much larger than they had anticipated, the expenses would be more than the four friends wanted to cover by themselves. These expenses were for such things as food, entertainment, police escorts, and insurance to cover potential liability. The question the four friends asked themselves was how much should they charge. As they did not intend to make money from hosting DVSF, they settled on an amount sufficiently large to cover the expected expenses.

As the number of attendees continued to increase, the expected income was likely going to surpass the actual events cost. So the friends decided that if any money was left over, they would donate it to some charity so no one could accuse them of making anything off the show. Next, they needed to decide on the proper charity. After much discussion, one of them happened to mention that the daughter of Dave Smith, owner of Factory Five Racing, had Cystic Fibrosis. So CF became the charity of choice.

The first DVSF had approximated 300 Cobras in attendance with almost 400 Cobras for DVSF II, with 300 plus for each of DVSF III and DVSF IV. The show is still said to be the largest gathering of Cobra in the world.

Prior to DVSF IV, Ed's daughter became gravely ill, which weighed heavily on him. Unfortunately, between his daughter's health issues and with the event now being so large, the friends decided to end their efforts with DVSF. It was at this time the Ohio Cobra Club, a 501 (3) (c) non-profit organization, took the event over and it became the London Cobra Show in 2005. Since the beginning, the venues have remained essentially the same and Cystic Fibrosis has remained the club's charity of choice.

The London Cobra Show, gives homage to both England and Carroll Shelby. London, for England which was the home of AC Cars, builder of the car chassis and body and Cobra for Mr. Shelby, as he combined a Ford V8 engine with the AC Cars chassis and body to give us the Shelby Cobra, that we all have come to love.

It is great pleasure to be able to say that over the years, many great friends have been made, thanks to the show. In addition, the show has allowed donations in excess of $1,125,000 to help fight Cystic Fibrosis. The Ohio Cobra Club would like to thank everyone that has made a donation or has purchased raffle tickets for helping support research that is working to find a cure for cystic fibrosis! Please visit the Cystic Fibrosis Foundation website, for additional information about CF.

The Ohio Cobra Club ad the London Cobra Show are governed by a nine-member Board of Directors. To contact a board member, please see the contact tab.
