What a coincidence that Mark just posted "How to Draw People on the Subway," as I have been trying my hand at just that. Inspired by the Urban Sketchers and the manifesto to CAPTURE THE MOMENT I've been carrying my sketchbook on my commute to and from my downtown office.

Have fun Sketchers, and thanks for the inspiration!
