Thank you everyone for your help. I contacted Keith with Sierra Dive Center, and he invited me to join them at Sand Harbor last Tuesday. When I went to the shop a few days before to rent tanks and weights, an employee recommended I take the High Altitude class which included all rentals, and a personal instructor (guide) for the day. It was a bargain for $125.
I have never had an issue diving wet in cold water with being cold. I have thought about buying a dry suit for the ease, but if I did, my wife and 3 kids (who also dive) would want one... Definitely not on the scuba budget.
The dive was AWESOME! clear water. Cool rocks. Well preserved wreck. Storm rolled in and created whitecaps, but under the water, still a paradise. ..
