With my scuba lessons. My wife and I both decided to buy some new snorkle equipment. Next thing I know we were both signed up for open water scuba certification lessons. You guys just thought a Harley was expensive - start buying scuba equipment.
Anyway, we finished our confined water and classroom instructon a couple of weeks ago and completed our forth and final open water dive today. We are both certified not as open water divers!
Let the adventure begin!
