No matter how long you've been watching racing, the first moments after seeing a hard crash are always frightening.
You don't know if the driver is uninjured yet, and you get the "Uh oh..." feeling in the pit of your stomach.
Wow...I hope he's OK.
The 2010 season had a few of those wrecks, but we want to know: Which one scared you the most?
Carl Edwards flipping Brad Keselowski at Atlanta was certainly the most memorable wreck of the season, as it's been replayed hundreds of times.
But was it the scariest? A case could also be made for Edwards/Keselowski II (at Gateway), Elliott Sadler's hard crash at Pocono (when the engine came out of his car) and the AJ Allmendinger-sparked wreck at Pocono which resulted in Kasey Kahne getting airborne.
One of the lesser-replayed wrecks, but still scary nonetheless, was Dennis Setzer at Talladega. He caught fire and rode the fence in the Nationwide race, and for a moment looked as if he would leave the track.
