I had a meeting today, and the commute afforded me the chance to do some Metro sketching, plus my first time sketching on a bus. Sketching on the Metro is routine by now; find a seat affording the best views and know which stops people generally board and leave the train. The bus, however, was completely new; where to sit, what angles to draw from, and how fast to draw.
The first drawing is from the Red Line on the Washington, DC Metro. The second is from the J2 bus line.
