Thanks Ringo for your inquiries. We have decided to do our OWC here in OR to get some experience w/ dry suits and also our instructors are really great. When we get to Thailand we will do some fun recreational diving and also pursue our AOW, still comparing options on that. We have been to Kata Noi before,(just vacationing, pretty beach, less crowd)and I saw from some of your other posts you have friends who run business there. For fun dives to 'get our feet wet' befor AOW, ideas?
