I saw this dead fella on my way to work the other day - right in the middle of the path. Big sucker, ain't he? Sometimes when I'm riding home these dark autumn nights, I can hear the rats running in the grass and underbrush near the bike path - glad I don't see them!
On the other hand, there is beauty in the night also - here's a nice shot of the Monument and the Moonlight. Washington, D.C. is a pretty city at night, with the various memorials lit.
