I am scheduled to be teaching a class in Santa Rosa the weekend of January 17-18. I may go there a day early just to get in more diving. The class is TecReational Diving, a PADI distinctive specialty that focuses on buoyancy, trim, and advanced kicking techniques (frog kick, modified frog kick, modified flutter kick, back kick, and helicopter turns). I don't know yet whether we will dive the Blue Hole, Rock lake, or both. It doesn't matter for this class. My preference is always Rock Lake. The class only requires four dives, so we will be doing other diving as well, with those dives as yet unplanned. If people are interested in joining us for the weekend, let me know.
