Maine is, however, and unrestricted open carry state. With the exception of federal buildings and such, obviously. I grew up in Maine, it was nothing to see people open carry. I was hunting with my dad one year and we stopped to get breakfast at a diner. I was sitting across the table from dad with a revolver on my side.
BTW, Maine has a very reasonable system for getting a CCW. It took me all of 2 months from the date I mailed in the papers. The papers took me all of 20 minutes to assemble.
