Today's Pittsburgh Post-Gazette has a collection of my travel sketches on page 2. You can click on the image above for a closer look at the printed page, or you can visit their website for their online version of the feature.
(These were not from my daily sketchbook - I had so much fun filling a page there on the way to Boston at the beginning of July that I decided to make lots of drawings in another sketchbook on the way home. Five pages of drawings and comments were distilled, transcribed, and rearranged for this.)
Update: Among the wonderful responses to this set of drawings was an email from railfan Patrick Rieger, who works at the amazing Miniature Railroad and Village at the Carnegie Science Center in Pittsburgh. He was able to answer a couple of questions I'd had en route:
The answer to your question about the long pause at Harrisburg
probably was a crew change, and the water tanks on the cars are topped
off and garbage removed.
The long bridge over the Susquehanna is the Rockville Bridge, built by
the Pennsylvania Railroad in 1901-1902. It is the longest stone arch
bridge in the world.
