I agree with what most people have said. If it's a small stream that isn't well known, and especially if it holds wild trout, I won't mention it by name on any forums. On the other hand there's several streams I fish on a fairly regular basis that are what many would consider "famous". They've been written about in national magazines anyway (Spring Creek in State College, the Little Juniata, Penn's Creek, etc.) and I don't think mentioning them by name could worsen the tremendous fishing pressure those streams already get anyway. There are a number of streams around here that have never been written about and hold significant numbers of large trout and have hatches every bit as impressive as the streams I've named above. Those are the ones I won't be telling about...
