That was an odd discussion.
Don't eat any mushrooms you are not familiar with and normal people would be happy to show you where the best place to fish is because we are not not trying to "catch them all".
700 and something miles of trout streams in the Smokies? Ten plus million visitors a year? You can catch just as many nice trout near three visitor's centers I know of as on Noland and Forney and not have to hike up the Hyatt Ridge trail to Raven Fork to find solitude without loneliness and a good day's fishing. Since some folks seem to think we are not supposed to mention specific fishing spots I will only say that any stream that feeds the Ocanaluftee is a good bet now.
