We have been out there quite a bit this summer and would have been more than happy to give you a ride, but I probably won't be back out again until spring. Are you looking for a console rig or a tiller? I know where you can probably catch a ride in a CC PD rig and a CC GT rig (gt will probably be closer to duck season though). I know a couple guys out that way with tiller pd's, but you said you've ridden in a pd rig already. Don't really know anyone to set you up with that has a tiller gt setup in that area, but most people with mudmotors are friendly and like to show them off, just flag somebody down and tell them to let you drive.
You should try to holler at Caddo Dennis! He catches more bass on that lake than anyone I know out of a tiller pd setup.
He lives down there on the corner by crips. If you run the lake a lot, I'm sure you've seen him or met him. Really nice fella.
