Live Action Role Playing (or LARPing) is one of my favorite hobbies. LARPs are more difficult to set up and run than traditional table top roleplaying games (due to the character writing, setting, and costuming demands) so I get to play less often than I would like. I've run a couple of small scale games as well as one really big one.
I have pictures of more games than I have patience to put up. If you want to see some cool LARP pictures that aren't mine (a few of which include me ;) check out Kathleen's LARP gallery.
