They are definitely worth the drive, especially LBJ! I fish there a lot and it's a great lake. LBJ is clear to run all the way, just watch out for shallow points. As far as the fishing goes, find the grass and you'll find the bass. For tournaments I always stay at the La Quinta. It's a very nice hotel. Otherwise I just drive up in the morning. I've only been to Buchanan a few times so I'm of no help there. I have done well there in the river.
