The first time my father dove in Florida was in Key Largo in 1984 with Quiescence (dive operator). Since then, we have become regulars (myself more since I live in Miami). The owners have not changed - maybe more wrinkles and less hair ;)...Last weekend they invited me to their 30 year anniversary - music, beer, bbq, and friendly people - of course there was some Jimmy Buffet going on.
What makes Quiescence so special besides the fact they only take six divers per boat are the people...
Take a look at some of the photos of photos of the history of Quiescence.
