If the DNR wanted to stop it, they would.
You're kidding, right? After putting up signs, fencing, and threatening to have to close the trail, they need to do more? People complain because there isn't enough law enforcement, and then complain that there is too much. I know from experience that things are not always fair. Ever been pulled over for speeding and have to watch everybody go flying past at 70mph? People need to realize that somebody else isn't always going to be there to solve their problems. One thing for sure, most people are not going to put up with having to fear a snowmachine crashing and burning into their homes killing their family while they sleep, or have to pay for government agencies to baby sit to prevent rampant damage to public and private property. The bull needs to be taken by the horns or something is going to give. And if the DNR is truly ignoring the problem due to political pressure or whatever, it's only going to worsen things down the road.
