Richard:
I had a similar introduction to humidity. Grew up in Southern California and went to Navy flight school in Pensacola Florida in the summer of '69. I remember thinking, while walking down the jetway off the airplane: "I wonder why they've got the heat blasting in the middle of the summer." It only lasted a second because we were quickly inside the air conditioned terminal. It wasn't until I picked up my luggage and walked out the front of the terminal that I realized what we were in for.
Another humidity story: While in training in Pensacola we had a ***** inspection one day. Dilligently cleaned our *****s in our air conditioned dorm then fell out for inspection. Discoverd a few minutes later when we came to port arms for inspection that the humid air had condensed all over the cold steel of our *****s. Failed the inspection. Learned to pre-warm our *****s - attention to detail..... drop and give me fifty.... Aye Aye Sir!
