Hi, Jim
Well, welcome to Texas! I think you'll find that the place is full of pretty friendly folks. However, after Hawaii and diving four times a week, I might have some bad news for you. The dive opportunities are quite a bit fewer and farther between than you are used to. That doesn't keep us from trying to get underwater as much as we can, though. To Parrothead's list I would add a couple of quarries (one near Huntsville and the other near Terrell, Texas), the Comal River in New Braunfels, Aquarena Center (also in New Braunfels), and of course, the Flower Garden Banks National Marine Sanctuary, 110 miles out in the Gulf of Mexico (I'm a volunteer for the NMS, and I live 8 hours from the coast!) In short, you may have to drive quite a bit more to get to dive sites and they will be a LOT less pristine than what you might be used to. However, there are some really unique dive sites and opportunities if you'll just remain flexible.
I invite you to take a look at our group, the Christian Divers of Texas (
www.cdot.1hwy.com). We try to get daytrips, weekenders, and even some more extensive trips together, particularly through the spring, summer, and fall months. Come share the fun with us! We'll be glad to show you around some of the Texan dive sites.
Take care, and as I said before...Welcome to Texas!
