A recent news broadcast said that according to some study or other, Colorado is the most fit state in the nation. It has a thriving economy, with a very low unemployment rate--below 4% the last I heard. But this diving thing has been going on a very long time. I first heard the statistic from the scuba instructor who led my Discover Scuba dive in Hawai'i in 1985. When I first got certified back in the last millennium, the city of Boulder had 3 full time dive shops.
