You would also do well to tie up some Niagara eggs. Erie tribs can be a funny place to fish sometimes, especially in PA. Tons of fish, and most of them have seen lots and lots of flies and bait. Nymphs tend to work best for me, but eggs ans spawn will also produce. Unless the water is high, stick with small, drab pattens. If you are going to PA, don't forget your patients (with other fishermen), there are plenty of fish for everyone. Try Crooked or Racoon... small streams, big fish in good #s and few anglers.
