Well, you're a better person than me when it comes to the thermostat. I keep it in the high 70s downstairs. I'd get cranky in the 80s!!!
We had DGS here late this morning for a few hours. After lunch, we baked cookies in DH's truck on the dashboard. Took over an hour and a half to "cook" them, but they didn't rise. Smelled great in the truck! We also tried to fry an egg on the sidewalk in a pizza pan. it was more baked than fried.
