In the spring and fall there is a great night bite, but summer and winter I can't get anything after complete darkness either! Usually a really good frenzy right at dark for 30-40 minutes if your in the right spot! It's not just you, I saw a couple oldtimers going out with lanterns the other night! Was out tonight, too flat for me, got smallies and few big perch, one good eye and lost a couple at the boat! (All eyes 9:10-9:35)
