"When I graduated from college, I sought out the cheapest rooms or apartments I could find. One of these put me next to a freeway interchange in Oakland California. The experience of living there, biking everywhere and reading the book The Power Broker by Robert Caro, changed my life and made me appreciate all the issues associated with transportation. I saw exactly how and why the freeway interchange gutted my neighborhood and how the main obstacle and danger to bicycling in urban areas was cars and drivers. This was the early 1990s when many people were waking up to these same issues. I participated in some of the first Critical Mass rides in San Francisco and the East Bay and started giving them my transportation cartoons for flyers and posters. I also discovered the (now defunct) “Auto-Free Times” and Alliance for a Paving Moratorium in Arcata, California and started sending them cartoons as well. By 1994 it had become a major theme in my work."
