Not sure I can put it into words. But I would guess the crack addiction comparison is pretty close. It's an obsession! Can't get enough of it! Closest body of divable water is a 3 hour drive (and by divable I mean not against the law to dive it, some of you may not think it divable--0 viz) and we still manage to drive there every couple of weeks if we're not diving somewhere else. Why do we do it? Just to be underwater breathing through a reg. Yes, even being in a pool provides a little bit of a fix. Hey, have you heard they think they found Atlantis? I think we need to move! It's not any one thing. It's everything--the caves, the wrecks, the fish, even the rocks in the lakes we dive and the occasional catfish we might see every 1/2 dozen dives (can you believe there are fish down there?!?!?!?). Good thing we're diving Saturday, it's time for a fix! Oh forgot to mention the missile silo--not much to see down there, but it's a dive!
