Lots of good fishing in the area. Lots of lakes, rivers, streams & ponds. The Delaware and Skuke also get migratory species like shad and striped bass, with some monsters in the spring that can be caught from the shore.
There is a TV show called City Limits Fishing on .vs which does an episode on Philadelphia.
The Jersey shore is an hour ride away if you like salt water, buses and trains go from Philly to Atlantic City several times daily.
Good luck!
