I like having the Rolling Steel Tent's doors and windows open. Mmmm, fresh air. But rain puts a (nyuk-nyuk) damper on that, and the van quickly turns warm and muggy.
A few days ago, during a prolonged thunderstorm, I dragged out my 12 volt fan. "I don't know what good this will do. Muggy air pushed around is still muggy."
I was wrong. The humidity might not be any lower, but it does feel better. It takes me back to un-air conditioned childhood summers in the South, sitting smack in front of one of our many fans. I'm glad those days are over.
