A Tshirt is usually my souvenir for whatever event I'm at. I have hundreds of shirts, really only a couple I won't wear due to be irreplaceable. I figure if one gets trashed I'll replace it at the next event I go to.
That's pretty much what I do. Whether I'm at a concert, car show, drag race, or a cool vacation spot.. im dragging a new t shirt ( or shot glass- don't get me started- lol!)
