Unbelievable experience presenting and leading an urban sketching workshop at the National AIA convention in Philadelphia to architects and creative designers from around the world. Had the pleasure of meeting and leading sketchers from Disney, St. Louis, Albany, Beijing, China, Libya, Denver, D.C., San Francisco, Seattle, etc. Such an honor to pass the phonon of urban sketching to spread around the world. Got a bit emotional when Peter Bohlin (http://bcj.com) pulled me aside right after my presentation and told me I was a "special spirit". Thank you Frank Harmon for having faith in me and giving me the opportunity. You are one who "sends the elevator down for the younger ones." Thank you Luis E. Aparicio and Briseida M. Fernandez-Agosto for leading the sketchers as well and providing me with incredible warmth and inspiration in your beautiful city. The Dominican symposium ripples are making waves.
