I haven't run across Flickriver before. It seems to be a place to organize Flikr photos into some kind of a theme. This theme is George Washington Slept Here, and it includes a photo of the Braddock expedition monument in Braddock Heights, MD. Can't read the plaque? Here's a close-up.
It was much nicer this morning than yesterday. The humidity was much lower, making for a nicer run. Of course, I only did about three miles, so that helped.
