I love fall time too. I work outside all year round, and I admit, summer is now my least favorite season. After moving to Arkansas I've experienced weeks of high 90's with almost 100% humidity without rain each summer. It makes work that much harder. I've found placing a wet bandana on my head and keeping it wet throughout the day brings enough relief that I can make through the long work day. Thanks for sharing.
Yep, I soak my cap in cold water every chance I get to keep my head cool. I also keep spray bottles of water around to mist off and try to dissipate heat. It definitely works. I don't envy your Arkansas heat! Iowa is hot enough...
