How Do YOU Know It's Fall?

For me it's not a date on the calendar, or back-to-school, or colored leaves.

All those things are duly noted, of course, but what really tells ME fall has arrived is my skin.

I can go weeks during the summer months without putting on my Oil of Olay face cream, and all summer long I only truly need to moisturize the rest of me when I shave my legs or have been in a pool or ocean.

But then comes a day in mid- to late-September when, suddenly, I feel a slight tightening on my face after my shower. Time to moisturize.

Time for fall.

What's your harbinger of fall?
