Yeah, I am sure all of us sleds heads have had similar experiences with bizarre people, situations, etc. I personally have even saved a few peoples lives over the years and I'm NOT even a cop. Imagine that!
Part of the reason I snowmobile is to get away from people like you, no offence. It just another set of rules being jammed down your throat for what??? So I can feel safe from who exactly...??? the 60 year old riding their junk piles on the trail. Sorry man it just adds to the atmosphere.
As far as people doing stupid stuff on their snowmobiles with their kids what business is it of yours? I see stupid stuff every single time I ride. I see it in the parking lot before I start riding, after riding on the way home, etc.
You would be wise to read.
