Many years ago I moved to Maine from a lifetime in Miami. I learned some very important lessons that winter.
1. Miami does NOT prepare you for anything less than 65F that lasts more than a few minutes.
2. There are not enough layers to insulate you from the cold of your 1st real winter and still allow for movement.
3. Mainer's wear shorts and t-shirts any day over 50F....Tank tops if sunny without a breeze!
Then I noticed something magical happened, I don't know when but I suspect it was in that first spring. The second winter, I wasn't cold. The following spring on the first day at 50F I found myself in a T-shirt with the windows down while heading towards the beach! So I can say honestly that your body acclimates, I can no longer deal with any temps over 80F. I moved back to Miami for a while and hated the heat, and some time later I spent years in Dallas, Tx and despised every single day from around mid March to Thanksgiving. Winter is not bad, at least you can dress for it. I don't understand how y'all down south manage to survive summer, and I've seen some of you SMILE in 100F+.
But hey, to each his/her own!
