I remember being a little kid and my uncle going to the outback to meet a bunch of people from an archery magazine he used to submit stories to.
When he brought back photos of a bunch of dudes drinking beer in their underwear on their porch, I thought they were a bunch of weirdos but he said it was so hot in their shack it was cooler to sit under an awning outside.
This was in the late 70s or early 80s so I don't imagine there was a lot of AC anywhere.
No, not much aircon then; certainly not in the country. Sleeping under wet towels in summer was a good tip I got from a country raised gal.
Haha, outside in their undies! All I can think of is mozzie bait!!
