Started riding with S. at the Bastille. Rode down to Sandcastle-Costco, encountered YC and enjoyed a brief hello in the sunshine. Reversed and noticed that as the sun went behind the ridge, it became noticably moist-chilly (as if in a fog) between Keystone Metals and Becks Run Road.
The Monongahela River was calm and glassy, and there were fantastic reflections on the water.
When we rode across the Ft. Pitt bridge and looked down onto the river, you could see the reflection of the contrails overhead. I don't remember ever seeing that before.
