Somebody certified you to do what exactly? Did they know exactly who you were when they did it?? dick I have advanced, Night, cave and underwater ecologist certifications- I know, isnt that weird? im not always a nut, i do try to accomplish things as well on the side. I am definitely rusty in all since I havent been on a dive on at least a year, though i think I could jump back in with a few reminder lessons beforehand from a GOOD buddy.
