Well it absolutely is up here. 15 years ago we (dirtbikes, atv's, and 4x4 truck sized things) had almost unlimited use of thousands of acres of commercial forest land logging roads, skidder trails, abandoned rail grades, etc.
In the past 5-10 years the sxs tourism has been promoted heavily by hotels and bars to boost their minimum wage employment numbers and as a result the amount of traffic on the trails has blown up and as a result the logging companies have slowly closed off, gated, and bermed a good portion of secondary access trails and we've lost a large chunk of usable area. They are only required by law to allow foot traffic on the land as part of the tax break, wheeled traffic was at their discretion and it hadn't been a problem till the sxs thing took off. A lot of the idiot riders are from out of the area and don't care about littering and tearing up "wetlands" which gets the logging companies in trouble when it happens enough, and it does. They also don't respect private land, gates, berms, etc. and continue to get more stuff closed. It's not all sxs owners, but it's enough of them that they have caused permanent damage to the amount of land use we've got.
Don't get me wrong, I think a sxs would be fun to have, but I have such a bad taste in my mouth from what they've done here that I doubt I'll ever own one.
