Crossbows are illegal in Maine.

In New Hampshire it is legal to hunt with a cross bow durring the open firearm season. It's illegal durring the bow season though. They make you jump through hoops to get the permit though. You can only be issued a permit to hunt with a cross bow from the Fish & Game headquarters in Concord NH. The cross bow must have a draw of at least 125lbs.
This is the first year that they've been legal so I'm not sure if that's what you have to go to Concord to get the permit. It seems stupid to me. Tagging the deer is done the same way as any other deer. Hopefully next ear they'll make it easier to get the permits. I as a bow hunter agree that they should not be allowed durring bow season due to the advantages that hunting with a cross bow. Drawing on a deer can be the most difficult part of bow hunting and it's eliminated when using a cross bow but I don't believe that you shouldn't be able to get the permit where you'd buy a regualr liceness. That's just my opion though.

Where are you at SapperLohr? If you in the area we should get together for a hunt once firearm season opens up.
