I don't have as many years angling for smallmouth, but I love it no less than anyone here. Growing up my grandfather guided the Niangua, Osage Fork, and Gasconade for smallies, and my brother and I enjoy memories of many summer floats on those rivers casting pork rind eels and crawdads behind black bucktail jigs. There were the great days when we all caught multiple limits of bass, and each and everyone were returned to the water. And we had poor days too.
I agree with the others that more should be done to protect the smallmouth from meat head fishermen. I am hoping that one day my kids will enjoy the same quality of fishing I did as a kid. With conservation efforts I believe they can. If the necessary protective actions are put in place, and the fishing improves, I doubt fishermen will be any less tight lipped about thier secret holes. There is just something wrong about telling some irresponsible, reckless, jerk about something as sacred as your secret spot. I can tell you I went out last summer, middle of July, on a pretty hot day with my Grandpa and we both did very well. But I don't think I can tell you just where it was... although I do remember seeing quite a few cotton mouths!
