Photo from the Howl-O-Ween party.
The building we were at was just amazing for parkour. Lots of ledges, walls chest high and lower, tables, railings... I couldn't resist playing around a little. Particularly since I was dressed up as a hunter.
As a side note... duct tape is a really stupid idea if you want mobility... and your shirt not to lift up every time you raise your arms above your head. I still don't know how or why hunters have duct tape on them.
