Skylar is right. It is a multi-use trail there and is thus open all year to motorized recreation. It is also main firearm deer season, so the only time you can be in the woods on ANY motorized vehicle is from sunset to sunrise and between the hours of 11 am and 2 pm.
I seriously doubt that any hunter up here would shoot you. I know of no hunter that gets angry about a sled or ATV out in the woods when it can be legally, but let's have some respect and courtesy for the hunters. They only ask for 2 weeks out of the whole year to keep the woods quiet so they can hunt. Only 4 more days then it's our season for the next 4 months.
