That sure seems to be how it goes for me. Plentiful at the very beginning or very end.
I'm in Knox county if you ever want to float over and hunt a few spots with me?
had the same problem this weekend, one in the first 15 minutes then nothing for the next 2 hours of creek. we have a joke, thats more true than not, if you find a good one right away call yourself a winner and go home
