Now I do not have one, but I have been wondering if it is legal to do so. Also, can you carry a rifle around like Nick Cage carried his bow around in the movie "The Weatherman"? I personally wouldn't carry a machine gun for several reasons. The least of which is I would probably become a bit prideful about one under my suit. "Yea, thats right. Thats a machine gun, baby." Anybody know? My roommates and I are curious.
