I did live in FL for almost 5 yrs, so I know how you can acclimate. My DIL said she doesn’t go out after 11 am, but I give her a pass, since she is 8 months pregnant. Fayetteville won’t be any better, so we will plan our visits accordingly. She goes to see her family a lot, in Philly, and it is easier for us to just drive there to visit. I guess what I like about New England is that the weather is so changeable. Even the winter cold has varaiations, and it is not as long of a winter as in the Midwest. The months of relentless heat is what I hated about AZ, too. Same every day.
My sore throat is gone, now just a head cold, but I am not sneezing or achy.
