Track at night adds an extra layer of exhiliration.  The sun setting behind the Stanford tower, a sliver moon falling into place, and a track full of sub 4 milers, techies trying to finish one lap, and boot camp moms trying to lose just 5 more pounds.

At night the track just seems to sparkle.  Reminds me of awesome runs at Grove City, CMU, Memorial Field, Harvard, Tufts, and now Stanford.
