The Illinois Association of Snowmobile Clubs says the trails are not open. The trails are open from December 15th through March 15th only when four inches of snow is on the ground. But the association says already snowmobiles are out. This is dangerous due to hunting season, the trails are not finished yet, and trail markers are not up. The only place to legally ride a snowmobole now would be along roadways, which can also be very dangerous with all of the culverts and other hazards along the road.
