>> That's how this yard is too. Squirrels love it (so do opossums)! <<

I like watching the squirrels run overhead. I am much less fond of possums, which we also have.

It does, because then sweat doesn't evaporate, so the body can't cool itself. Also muggy weather makes skin and clothes stick together unpleasantly.
