Ok here is my question. I am on vacation in Florida right now. There is a gun down here that I would like to buy and I was wondering if I can drive back to New Hampshire with it. I am looking to buy a Colt AR 15 (6920) brand new and it has colap stock and flash hider (assault weapon). I was wondering if I can stop and stay at hotels or do I have to drive straight home. If I were to stop in PA would I be breaking any laws. I have pistol permit in NH and no lic needed for long guns. Also is there any states I should avoid if possible, or which states can I stop and rest with out a problem. Will be travelling mostley on 95 so GA./SC./NC/VA/DE/NJ/NY/CT/MA/then NH may have missed a few.
Any input on this would be helpful
thanks in advance

F.P.
