It's really not that big of a deal where it is.....in Wisconsin, Minnesota, Michiagan, etc, the rivers are pretty much filled with huge smallmouth. Makes Missouri look like the little league in comparison. Even with the short growing season those fish live to 20 years old or more. You wouldn't have that down here with the eat anything that swims mentality.
Edited to say that they consider walleye THE fish to target. Serious bass fisherman are many times from out of state.
