Also have been to Blue Lagoon and think the League City place would be similar. Will go there soon to test out some long fins. I will see if I could at least try it out pretty soon. I have no dive buddy so that makes it hard. You are so lucky to go dive where some of the famous pirates were! I hope you have a great time!
I will work on my setup and you can get your computer repaired. Will be looking forward for a future dive.
Are you going to live in Houston? If so it would be nice to join the Bay Area Divers, they have local dives.
