The trend toward subdued color palettes. Every new home is decorated in “millennial gray.” Most cars are black, white, gray, or silver. You have to go out of your way to find bright, colorful clothing or furniture. It’s incredibly boring and I can’t wait for the pendulum to swing back the other way.
Depends how high into the triple digits, whether there’s shade and water available, how humid it is, whether air conditioning is an option, etc.
I would probably choose triple digits. I do love cold winters, but a dry 104F with a cool place to swim and big, shady trees is splendid. Beyond about 110F gets miserable, though.
