Some municipalities get really anal about the shakedown scene, they aren't getting their tax cut so they don't allow or shut it down. When i first moved to Philly, i went to a futhur show at the Mann Center. The The philadelphia license and inspection 'cops' came through and shut down shakedown, it was really f***ing ridiculous. Since then, both in Camden(NJ) and S. Philly, shakedowns have been set up in full force and it's one of my favorite parts of the lot scene, even though I rarely buy anything.
