6 years ago I completed local SCUBA certification course (Reno, NV) but never went diving anywhere. In a few weeks I will get re-certified and plan to go on my first diving vacation. I have always wanted to go somewhere tropical and do some diving where there is an abundance of great underwater wildlife and scenery along with warmer waters (january?). any ideas or recommendations (with somewhat budget intentions, lol)? hope to be gone for a month or longer. thanks.
