Well, in the spring, as soon as the indoor temp hits 80 I turn on the ac, but it may just be the humidity because here in the height of summer I keep the house at 78/79.
You know my favorite part about The Stand (S. King)? Ok, besides the part where most of the population of the entire world dies...but when Frannie is worried about her father's body rotting upstairs. In the heat. And she's sweating in shorts. And it's like 75 degrees or something silly. At 75, I'm in sweatpants and a sweater. That's like Xmas weather!
