Diane Keaton at the Dam

I’ve had a few surprising celebrity sightings in my life: Madonna, so tiny, so blonde, eating next to me in a dimly lit Moroccan restaurant in downtown Manhattan; Flavor Flav making his glacial way through Madame Tussauds Wax Museum in Las Vegas while everyone behind him was forced to stand around and wait; Julia Roberts and Benjamin Bratt at the height of their romance, hailing a cab on Park Avenue South. But none were more surprising than the time, a few years ago, I saw Diane Keaton at the Hoover Dam.
