i miss those... we used to have a few polaris's, a 400 and a 600 i think. the 600, i don't remember what it was called, indy something was flat out scarry. if you got something packed, it would be more than willing to throw you off the back if you didn't have a good grip. but hit some powder and it was all over, if you even had to slow down for anything it was over. it would bury itsself.
i rode my friends old 400 yamaha phazer, thats an insane little sled, it doesnt' weigh anything, and has pipes and carbs.
if i ever really want to get serious about drag racing, the snowmobile class is the way to go.
nice looking sleds there!
