Duck,
If you ever find yourself in base for a couple days, you might want to check out Blueberry Hill. Easy ride to the Delmar Loop on the train from the terminal. Chuck plays there six or seven times per year. Oddly enough, in the "Duck Room". Only a couple hundred seats and they always sell out.
I worked as a stagehand during college and one of the guys I worked for mixes these shows so I've been to a few. It's a treat. I'd highly suggest going if you appreciate his music because he's had some health problems recently and has cut his schedule quite a bit.
