hmmm...not a bad idea....btw, how challenging are the dive
sites? I'm going to suggest that we avoid those with strong surface
currents because we are all rusty, and some will be newly certified
on top of it. I'm thinking relatively shallow and calm sites, with
good visibility.
Oh, and the rusty ones, including myself please at the very least
go do a proper refresher before the trip. And learn how to deploy a
safety sausage properly (everybody should have one, even better if
you stencil your name onto the safety sausage), if you don't
already know how to.
I know I'm nagging, but I'm quite anal about safety issues (and I
will nag a lot more during the trip)
