Ive been racin motocross since I was 4, I know what you mean. I just recently quit racin after I got married. Motocross is one sport that if you ever have a chance to take part in it, it becomes part of you.Trust me I did my share of Dumb things LOL I have been Riding Dirt Bikes from the age of 5 and I'm Lucky to still be alive with all the things I have done and I pay for it everyday with old age I though I was Evil Knievel when I was younger and I know what the ground tastes like.
My body has been to hell and back and I still ride, but no racing now, I do a lot of Dunning on my Quad.
