Seen along I-70 on a tractor-trail's mud flaps while driving home from Indianapolis, Indiana:
Some of us have and most of us have seen the license plate frames "I'd rather be snowmobiling"
Both rear mud flaps said "cow mobiling"
Yes, it was a cattle transport trailer.
No idea what brand of snowmobile the owner had, but does it have "beefy" suspension?

There is a difference between a true snowmobiler and a person (qualified by: fool, idiot, dumb ass, etc.) riding a snowmobile.
True snowmobilers are a benefit to all.  They respect the trails opened to us by the Landowners.
While a person (of questionable qualifications) riding a snowmobile needs a little attitude adjustment and some education.  We all end-up paying for their attitude and mistakes.
New riders and/or beginners have the opportunity to choose which category they wish to fit into.
You choose -

Did you hear the one about a person riding a snowmobile that was less than courteous to a cross country skier?
A group was riding along a trail and caught-up with a cross country skier.
They slowed-up, proceeded around the skier, and continued.
Seems the last person riding a snowmobile felt inconvenienced by having to slow down and share the trail.
So this last person gave the cross country skier the one-finger salute.
The cross country skier just happened to also be the Landowner.
Now thanks to some dumb ass person riding a snowmobile, the trail is permanently closed and will not ever be re-opened during that Landowner's lifetime.
This is a true story.  Do not know where this happened though.
Moral of the story.  If you cannot share the trail, stay home, you are not welcome on any trail.
