No worries on South Street.
Not always the case. Just a couple years ago (maybe less?) a few stores were raided for carrying 'little baggies' or jewelry bags. Just ridiculous
That said, there is an abundance of super thin, cheap glass in that area
If you're in the Philly area, Artifax and a fairly recently opened shop Creep Records are worth checking out IMO. The latter sells vinyl records and music upfront and has a pretty nice glass shop in the back.
JDSupreme, as far as I know, the Operation Pipe Dream scandal was basically a case in which a few states (PA being one of them) were willing to cough up money to prosecute on the basis of paraphenalia being shipped in between states. I think this is the reason that its generally tough to get glass shipped into PA (I know I've had issues
). Not sure if this has any bearing on the legality of glass shops per se but clearly displays an unwelcoming attitude towards these shops. Wishing PA was a little more glass friendly here as well though.
