I've noticed that, Bob. Vacationing in Hawaii with the odd day, VERY odd day in the high 60's and people wearing jackets and sweaters - in beach weather!!
I do NOT handle extreme heat very well at all. 80's are full blast air-conditioning weather for me.
High 70's I find quite distressful.
Without converting. I'm guessing that is winter here ...
It's been raining a lot here, the 5 minute attention span climate change believers think the world is ending ...
