I fish Palestine most of the time, when not traveling. The comment about fishing the bridge is really funny, but I hate to say a good one. Depending on what kind of boat you are using, I would consider trolling. I run in a bass boat and easy to troll and get around but the fish are coming back to the bridge. Here is a link to one of my trolling the bridge videos. I believe that I talk about my setup in here but just in case I do not, I use a heavy weight, a jig, then another weight to start with. Then I put a 1 foot leader on it, and another heavy jig. The reason for this is that I am trolling around 1.5 mph the the two heavy weights keep the line down at aprox 15 feet of water. I started putting a jig on there as well because I keep getting a hit on the weight by the crappie. Once you start moving, the jig will trail shortly below the weights and I slay them at the bridge.
Now, with that said, the biggger fish are in the stumps. I saw a recommendation to get Tom's chip with the boat lanes in it and I also endorse that. I have it for both of my console units. If you get a chance, look at this video and then look at the other videos as most are on Lake Palestine right now. It is a great lake and have caught a ton of 16 inch crappie. Biggest so far I believe is a 2.78. Let me know if you need some help.
