I raced a Harescramble last Fall w/ a buddy of mine. I was on my CR250 he was on his CRF450.The course consisted of grass track and tight nasty,muddy woods As I came around on lap #2 there he was, on the side of the course. He had boiled all the coolant out of his bike in the woods section.There were more than a few 4 strokes that DNFed the race due to over heating. Nothing like paying 50.00 to spectate
