Welcome! There's this - Houston JeepPeople Meetup Message Board - Houston JeepPeople Meetup (Houston, TX) - Meetup
And this - http://centraloverland.com/
If you are the overlander type, which is me, go here, but be warned; YOU WILL SPEND ALL DAY ON THIS WEB SITE! Expedition Portal Forum
Now, the first web site is where they have something going on practically every weekend related to Jeeping. Nice people, and I really like them. I just wish I had the money to drive over and meet with them every two weeks, but right now, I just used most of my my tax refund to pay off my travel expenses from last year, and I will be using the rest of it to pay down my Scout conversion. Otherwise, I'd be out there.
P.S. Go here in case you have a break down and need help. It's a directory of people willing to help - Rescue directory - Houston JeepPeople Meetup (Houston, TX) - Meetup
