Scuba Lessons

I would get certified (I am not, but I my dad is an used to be an instructor so I got all the free instructions I needed and ive been below the surface a couple of times)

just because it is a different world down there and different rules apply
especially if you plan on taking the missus down I would want to know that I was prepared to handle whatever situation might occur (keep in mind, once you get married you are no longer responsible for the safety and wellbeing of one person but two, plus whoever gets born into your new family)

the initial cost of buying all the gear is high but how says you have to buy it all at once or that you have to buy it new?
or that you have to buy it at all, im sure that where you are going there are rental shops and there might even be some in minusooooda
