Know the feeling. One other lake a alternate fishing is hit or miss - mostly miss - but when fish are on, they're on big time especially for large crappie and numbers!my latest trip, which netted me 1barely legal redfish.
Funny though, this angler I gave some of my creations to before that day, met me at the parking lot and said he caught over 30 fish from a few different shore areas. He doesn't have a boat nor knows the depths but seems to do very well even with those limitations. He hated it when one of my lures he was catching fish was lost to a snag (stump) and then he caught fish on a chartreuse curl tail grub. (I pretty much don't use curl tails.)
Go figure.
