RE: To ATV or not to ATV, that is the question.
If its legal and it helps use it. An atv is a tool just like a gun or a chainsaw, it can be used properly or misused depending on the person in control. People like to bash atv's just like guns, but just like when a criminal uses a gun in a crime, it is not the fault of the gun, as when someone goes out of bounds with an atv it is not the atv's fault. It's all about responsibility, and to lump all atv users into one group is like throwing all legal gun owners in with the criminal element.
Depending on the area you may want to stash your atv out of sight, some anti atv'ers have been known to slash tires (which is a dumb thing to do in the woods where everyone has a gun). Get you a camo or earth toned atv cover or tarp(help protect it from the elements also), or set up a dome tent you can park it inside of to keep out of sight and limit a thief's temptations.
Good luck, have fun hunting, don't sweat the small stuff.
