I keep a list of stream names I have fished. If I ever fished it, it's on the list.
I sorted them by name and "un-named trib" is a clear #1. hehe. "Laurel Run" is #2.
Well, I suppose that's ignoring "branches". For instance, there's a lot of West Branch of _____, east branch of ____, but _____ is different. I suppose you could say the same of "unnamed trib to _____".
My favorite branch name, though, is just "The Branch". Someone was really original when naming that one...
