This weekend I got a photo of some parking lot graffiti that I did in Santa Monica when the Derby Dolls were still homeless a month or so ago. We were having a practice in a beach parking lot and I drew out track dimensions with chalk. I then drew a blocker(no photo available)and a jammer to indicate where everyone's supposed to set up for scrimmaging. Below is my jammer drawing:
The photo is off of a skater's cell phone. Probably some of the best work I've ever done.
