I saw in another thread Adam mentioned he may be at the Bean Blossom Blues Festival in Indiana this year. Its Aug 28,29 and is a great time. Killer blues on the main stage, and lots of jamming everywhere.
If you go, make sure to stop by Cabin 12 to hang out and jam. We're usually going until late on Friday and Saturday nights. We've been doing this for years and it gets better every time. We've had Mooncat, DennisG, PT, Deak, Ronnie, and others I can't remember right now stop by to jam.
Here's a video of one of our late night jams with DennisG who stopped by after playing on the main stage.
