I remember years ago, my brother had a couple of sleds, a brand new Arctic Cat El Tigre 5000, and an old SnoJet Thunderjet. I don't remember what motor was in the Thunderjet, but it was stupid fast. The Arctic Cat was no slouch either. Almost got me to get into the sleds, but I had no place to keep one, and didn't want to go out and buy a truck just to haul it around. Motorcycles were my addiction in those days.
