I was riding in central Wis. (Antigo) on Sunday when we came across a 98' or 99' Formula Z sitting on the side of the trail. No track on it! Track was ripped right in half, like it was cut with a knife. Track looked brand new, not a hole drilled in it or anything. I was puzzled.Of course, i was riding with my dad, who happens to ride a Cat, and always has. So i knew i was going to have to come up with somthing good. So at the next stop, before he could even get a word out i said "See i told you those Ski doos are fast. Blew the track right off." He didn't know what to say. Got him!Hope the owner gets a new track out of it! Good luck if it's yours.
