It might be best to keep your expectations modest on the wild trout fishing in Lancaster County. Yes, there are more streams than you'd think for that area, and even a few "Class A's," but it's my experience with them that they don't really fish like Class A's. It's been a good bit of time since many of them have been surveyed, and my guess is that if they were resurveyed a couple of those Class A's wouldn't make the cut now. Not saying they're not worth checking out, just that I wouldn't expect a day of huge numbers on them. If you have any specific questions on them, shoot me a PM...I know the ones in northern Lanc. County pretty well.
