I've had the privilege of living in different areas of Florida for many years and I have to chuckle when people say it's crowded here in TV in Winter. Any half way decent town in Florida is busy in the Winter; it's the climate that brings everyone South. I'm willing to pay the price which isn't much of a problem for me, I plan my day knowing that things will be crowded and enjoy the Summer when it's less crowded all the while thanking God for the beauty all around me. Regarding mail stations, we are rapidly moving toward digital mail so in the not to distant future the shrinking US Postal Service will be a thing of the past.
The heat and humidity in the beautiful Hudson Valley in NY could be brutal; the difference here in Florida is the most fantastic light each and every day. In NY we frequently had heat coupled with a haze that was depressing. Just my humble opinion.
