I'm from MA and I'm going to my parents place in North Conway for Thanksgiving. I mentioned this in another thread and a gentleman told me about a FREE range not far from me but it's in Maine. Can I cross into Maine with my handgun to go plink a few?? It will be in a locked box during my travels (unloaded and of course no rounds in the mag) I don't venture to Maine much so I have no clue of the laws.
