Need some feed back. The wife (divebuddy) and I want to do a road trip in November. We want to go to Balmorhea or Aquarena Springs. Neither of us have done the Scientific diver class required for Aquarena - and I am not sure she would be willing to go to class for two days. Question is as both are springs and have some similar characteristics (depth, temp, vis) - which is the preferred site? We are in Houston so Balmorhea is 8 hours driving eachway verses 3 1/2 to San Marcos. Appreciate any experience with this.
