Greetings, I am headed to San Antonio this fall for about 10 weeks for work and I'd love to find out what sort of tech diving options there might be (if any). I've read posts of lake travis being around 100 feet or so but nothing else and wondered if there were any deep quarries/springs or any tec charters that leave out of Galveston? I originally got my OW cert in Houston many years ago but have been on the NC coast for the past decade. Ideas would be appreciated. I anticipate being able to take a few weekends and run as far as possible to get some dive time in. Thanks!
