Played with a friend this summer. He has our teams in his very nice harley edition truck.... It wasnt so nice with a dozen cans of GG blown up in his back seat.
Besides the foam that gets every where its metal that ends up turning into shrapnel when it goes off.
Also dont try to ship them please. Had a guy we used to play with go up to the lady at the post office and ask. All she did was burst out laughing and walked away lol.
