Unfortunately, now that I've done some research and map quested the store, it looks like it's going to be way too far north for me to have time to swing by before I fly out. Oh well, I'm guessing shipping will probably end up being cheaper than the cab ride from the looks of how the store is from my hotel room.
Anyway, check out some of these newly released designs from Threadless...I think I might have to order up these first couple shirts:
Transfarmers by Ole Ivar Rudi
Penguins On Holiday by Philip Tseng
(Here's a great one for the kids in your life!)
