I'm leaving for Kauai in a couple days and I'll be there a week.  I
recently got my NAUI certification and I'd like some recommendations on
Dive companies on Kauai.  I'll be staying on the South Shore at Poipu

I plan on spending a few days on the Red Sea in Egypt in mid-March
doing some diving. I know nothing about the region other than the fact
that it's a premier dive spot. Where are the best places for diving? I

Does anyone have any home remedies for getting rid of the green
