Over the summer I spent whatever free time I had drawing. Usually during my lunch break I would get in to my car (usually to get away from coworkers asking dumb question about my sketches), flip on the radio, and doodle away. I would usually drive to another location in order to get a glimpse of something worth drawing. In the case below, I decided I would just stay in the parking lot and sketch the grass.
The only down side to drawing during lunch is having to go back to work.
