I really don’t know why, but SCUBA doesn’t have that ‘allure’ it did when I first got my certs. Now it seems to be a ‘nice feature’ on a tropical vacay or cruise. It appears interest is waning in some places. When I first took classes, my girlfriend, later wife and I had to wait for an upcoming class of 18 people to finish before we could register for one. Now, some classes are 3 or 4 students if any at all…..dive shops are offering special travel clubs to generate more classes for all ages.
