Maine
Effective January 1, 2006, with a valid crossbow hunting license, a person may hunt bear with a crossbow during the open season on bear and may hunt deer with a crossbow during the open firearm season on deer. The crossbow hunting license may not be used to hunt deer during the archery season, muzzleloading season, or expanded archery season. Crossbows are still permitted otherwise for disabled hunters. A person who applies for the crossbow hunting license, other than a junior hunting license, must submit proof of having successfully completing an archery hunting education course and a crossbow hunting course or evidence of having previously held adult archery and crossbow hunting licenses issued specifically for the purpose of hunting with a crossbow or bow and arrow in this State or any other state, province or country in any year after 1979.

Now is it just me, or does this seem odd. You can't use it during the archery season, but you have to have past Archery safety. Hey MDIFW, is it archery or not. Make up your mind.
