It is indeed unfortunate that in the space of a few short days, we get to read of some really bonehead decisions by snowmobilers. Sorry Rattler, and I know it is of little comfort to know you are not alone. There is another thread with similar type stories:

Back when my Dad had snowmobiles, back in the 1980's, on more than one occasion we would have someone come right up the trail to our house, and turn around on our front lawn. Dad used to say it was a good thing the garage door was closed...
Sorry for your damage, and I suggest contacting the Mt. Major Snowmobile Club
http://www.mountmajorsnowmobileclub.com/ and let them know what has happened and ask if it is possible for you to get "no snowmobile" signs for your property. I certainly would understand posting your property, and hopefully can be done at no cost to you.
