It's the first day of autumn in the Northern Hemisphere. Summers are hot in North Texas (where I live), but autumns, winters, and springs are mild and delightful. I had 26 years of snow, ice, slush, and cold weather. That's enough for one life.

Addendum: I got to wondering today whether "equinox" is related to "equine," which has to do with horses. Apparently not. The word "equine" comes from the Latin "equus," meaning horse. The word "equinox" comes from the Latin "aequus" (equal) and "nox" (night).
