There are also lots of charters available in NY on Lake Ontario from places like Oswego, Sodus, and Oak Orchard, among others.. Most of them run for trout and salmon but I'm sure there are some walleye and bass charters also, if that is your preference..
If you are in Eastern PA they might be closer for you than Lake Erie...
Even closer might be a Finger Lakes charter on Cayuga, Seneca, Keuka, or one of the other Finger Lakes.. There is a fellow named John Galke who lives I believe in Trumansburg, NY and comes highly recommended.. He specializes in 1-3 man charters.. You could probably google him up.
Hope this helps...
