No, they were not around docks, I did throw the Senko at a couple of docks, but no takers. A few of them came off the outside of a point on a steep, chunk rock bank, the others were in 5-10 FOW, near trees or relatively shallow rocky structure. Main drawback to fishing a weightless wacky Senko is that it takes forever to get down 10', so you can't cover much water. There are ways to weight a wacky rig, but then you get a fast sinking Senko, which may not be as effective.
My guess is after this cold front, they're going to want something different, hopefully jerkbaits will start working.
