Have you broused through the database here at RR. If not check it out at the top of the page. There is tons of stuff listed in there.
You could listen to Salem county NJ and Deleware County PA from your location. If you are into avaition I'm sure you could hear most of the traffic at Philly International with a small outdoor antenna. There are numerous GMRS repeaters in the area and Ham radio on VHF/UHF to listen too if you're into that. Or just throw the scanner in search mode and see what you find. You never know what you'll hear sometimes. Have fun!
