Philly streets at night....

Can anyone suggest any really cool, probably somewhat out of the way (city) locations to take some cool night time (hand held shots)? (Nikon D-7000). People, store-fronts, buildings, alleys, water.... it's all good! Please consider 'parking' concerns....and I don't mind paying $20.00 for quick, easy, safe parking.

I've already had a good time shooting down, and around South Street, as well as Penn's Landing.
Maybe here in Philly for another week or two.

I do appreciate it....thank you!
