Hold on a second... it even freezes in FLORIDA? Is there some part of
the US that doesn't freeze in winter outside of Hawaii?

Some parts of coastal California are relatively free from frost. I live in
Los Angeles proper and the coldest I've seen in twenty years is 40 degrees
fahrenheit. However, just 10-15 miles to the north of me in the San
Fernando Valley there can definitely be light frosts, but usually not lower
than 27-32 degrees fahrenheit.
