The days we picked, are because it will either be still pre-spawn, or the spawn will be starting. Pymatuming is the largest lake in Pa. For all of you, as long as fishing from a boat, you can use your Ohio fishing license, any where on the lake. Will be getting out more info very soon, as to which campground will be used, and there are cabins by the lake, that can be rented too. Saturday will be the big day of the event.
