I have a place real close to the 54 bridge, and it's really hit or miss. There's a couple of humps out there I guess where the old bridge pylon footings were, and I've caught them there, but this year hasn't been real good.
I did hear from a friend of mine that said his dad wacked some real nice ones next to the bridge piers about a month ago. Not sure which bridge though. Said they were in 30 FOW. I'm thinking the hwy 5 bridge over the Big Niangua, but that's just a guess.

Personally, I would stick to shooting docks. The last couple of weekends they were stacking pretty good. Having better luck on the sides under swim docks close to the back side.

Good Luck and lets us know how it went!
