Yep.I have zero issue with ATV's...its irresponsible users riding in illegal areas that I don't like. I use ATV's on many different hunts...especially the many open roads where I just don't want to take a full-size pickup.
Part of the problem with ATV's is enforcement of rules. The USFS does a horrible job of policing this, and the country sheriffs dept has more pressing issues than Jimbo driving off road in his 4 wheeler.
People started not following the rules, nobody got in trouble, so they just kept going off the trails.
This is a USFS LEO issue. Same reason why the BLM south of Laramie is a trash dump. No enforcement from the people in charge.
