Go to Erie PA. Great place for rainbows and steelheads. Was up there two years ago in Feb. and caught limit every day. I caught a steelhead weighing in at 11# and it took me 25 min. to bring in on a fly rod. The creeks are full of them.
I fish PA in the fall and always do very well - but I don't know about year around. I will warn you that some of the streams in the fall get very full of anglers - I often hear it called "combat" fishing.
