Don,
As Dee said, we've got a very active group here in Houston. We communicate through the following Yahoo Group.
http://groups.yahoo.com/group/Houstoncobraclub/
Sign up to keep posted on our activities. We always meets somewhere in the area on the second Saturday of the month. We also sprinkle in some "emergency" meetings from time to time.
Whatever you do though, make sure you go to the Austin event. It is a blast. Check the Houston Yahoo Group for caravan info. There will be groups leaving Thursday, Friday, and a few unfortunate souls on Saturday.
