I'm planning a trip to CC and my wife would like to scuba. I was cert. PADI in Long Beach CA in the 70s but haven't dove in 25 years and my wife has never dove. I still have flashbacks of swimming dozens of laps with tank, weights, mask, no fins and no air in the bc vest. I live in the Mid-west and have no interest diving in muddy lakes and don't get to salt water that often. I've read about resort courses on some of the cc web sites. How safe is it and where do they dive. Also, who on cc would you rec.
