Structure for sure!

even just a shadow might hold a nice shallow bass. just toss a plastic worm right on it; it will hit instantly probably. Then when its colder consider the fact-a tree trunk or somthing can actually bring heat down from the sun, into the water.

Most the time thou its just underwater structure they are near(dropoffs, lilly pads, any vegatation really)
tons of lures; plastics-worms and twister tails are pretty cheap; generally Id say worms=L mouth(purple for me), twister=smalls(chartruese maybe). Tons of lures for largies- one of the funnest is the top water! just twitch that plug along the top, and dont crap your pants when one jumps, wait to feel it, then set. It's easy to jerk it too fast. (even thou expensive, they don't snag up like cranks.)
Naturally only fish this in shallows, last one I caught was in maybe, AT MOST 3 feet of water! but maybe down to 5-10 might work; try hind lake(largemouth only) with top waters(south side). (maybe bring some polarized sunglasses too)
And whoever said they will hit anything almost, is a wise man. they even make a rat bait! lol ???
to sum it up, if u want to spend lots of $ try some cranks and spinners, but i seem to have just fine luck with my plastic worms.
Btw senkos for sure, action is great. ??? except i havnt caught one with one yet, still new to them. oddly I think a huge walleye cut my senko off one time thou.
rig your worm with a bullet slip weight, let it drop, reel it up, let it drop.
now senkos I have been trying weightless. just twitchen them.
