Bob:

There's a very nice museum in Erie dedicated to the "Niagra" and the War of 1812 and at least one small, but reasonably nice, art museum. The tip of that spur of Pennsylvania is Presque Isle Park and it's an impressive place to see the waves hitting the breakwaters if the wind is blowing.

Don't waste your time on the ecology center at the entrance to Presque Isle Park. It's designed for kids.
