That's the odd part, I was running around the outside of the track just putting along letting other cars pass me, etc. When I'd come to a jump I would goose the gas and get over the jump. I don't feel like I was going like a mad man. I was really suprised to see that I broke it. It looked like a real soft landing and all of sudden the wheel falls off. My friend that was with me was even suprised at how easily it broke.
