I'm going to purchase a snowmobile and was wondering what other steps I will need to take to make it leagal for ice fishing. I.E. Do I need to get it registered with the state or counties like a boat? Do i need snowmobile insurance or does homeowners or auto take care of liabillities. Last, does it cost extra to enter it into any parks such as Arapahoe National Forests AKA Lake Granby. Also, any pointers that would help a "greeie" snowmobiler would be greatly appreciated. Thank you!
