Well welcome back. I find with playful amusement this transition we all seem to go through.
When I first arrived from Minneapolis shorts short sleeve shirts and sandal were the uniform of the day unless the temp dropped below 45 degrees. I never dropped the panels on my cart until the temp dropped below 40 degrees.
Advance six years and at 60 degrees i am in long pants and layered with a sweater and jacket with the panels down on my cart.
So as you travel through The Villages and see those in shorts and sandals they are most likely seasonal residents.
Brrrr where is the warm weather?
