1 Hard question. Haven't been to any of those places. You should ask what type of dives, what types of sites. I'd probably pick Canada for its people and ice, or Florida for its caves (if I were cave certified), or the two others for the fishes and other attractions. Don't know what to pick. All.
2 A: Shore. Waves make me sick.
3 A: A dive club. Some are tech divers, I am not.
4 B
5 A
6 B What is a camera station? I would like to rent a prosumer grade (stupid term) underwater camera or video camera, though.
7 D
8 A: By car.
9 B: I have gear. I only need transport and gas.
10 What's the difference between lower and upper middle class? Shouldn't you be asking how much people spend on diving per year. Gear vs. actual dive trips. (andc no-one would answer)
