Hey Check this out http://www.bluelight.ru/vb/showthread.php?t=412113 . We normally don't allow "Who is near me?" threads but I can see this is a bit different. As such I've modified the title a little bit. good luck and I hope you enjoy your stay!
Hey im from pittsburgh! Im a little younger (17) and don't really chill downtown too much. But the southside is nice and you can't go to pittsburgh without checking out mt.washington (the view of our beautiful city is awsome) and having a primanti's sandwhich!
primanti's, they have giant sized sandwiches with french fries and coleslaw inside them.
what sort of suggestions are you looking for (bars or cultural stuff or restaurants or clubs)? when will you be in the city? i don't live there but i have spent lots of time in the city.
the weather will be rather random. it can be sunny and 65F one day and rainy and 35F the next. but i would say the average temp is prolly around 50F and partly cloudy.
i haven't lived in the area recently, so i am not up on the club scene any more. but check out http://hyperreal.org/raves/pb-cle/rom/ for some event listings. lots of them are shitty local things, but it should give you an idea. you can also check out the events forum here for some other ideas.
drugs in the US club scene are not as accepted as they are over there (from my experience). and it takes very little for the US to decide to revoke you visa if you get into criminal trouble. so you need to be EXTREMELY careful in this regard.
