Lots of water = lots of humidity,Wayne. Looking down at the surface from 30,000 ft in an airliner, Florida appears to be ½ water.
I joined the Army to see the world but they send me all the way across the state, 90 miles to Boca Raton, the Army Air Force radar school where I get yanked as an instructor.
Not to be denied, I took a 30 day furlough and hitch hiked around the country; to Los Angeles, San Francisco and then hops on military flights to Chicago and then hitch hiking back to my base.
One of the things that impressed me in the Southwest was the evaporative coolers on cars, a gadget that hooked on a window and used a wet wick to cool off the incoming air. Even some buildings had evaporative coolers. Cool and clammy.
Thank heavens for modern air conditioning.
