My preference would be away from other people, with beautiful scenery, many trouts, peace and calm. So that leaves out most of the generally often thought of places. I like it when I don't see another person for most of the day! Let alone another flyfisher.
Rivers, streams, glacier lakes in the south east corner of Wyoming is where I'll be, high up in the mountains of the Snowy Range.
Trouts don't live in ugly places.
A friend is not who knows you the longest, but the one who came and never left your side.
Don't look back, we ain't goin' that way.
