friend of mine was getting ready for a BMX race and as he was coming into the turn he hit aslick spot (it had just rained the day before) and he hit his head, about 15 min. after he got up and ito his car, he was still having trouble talking...now he has decided to stop racing, and just go street...i feel bad because he was top in his class and this fall made him quit. i dont know why im puting this up here, just felt like sharing...
