If you haven't heard of 'urban sketching, a worldwide movement of artists getting together to sketch together and maybe enjoy some fish and chips. Check out urbansketchers.org, and get in on the fun. I am part of the Urban Sketchers Atlanta chapter, and get to write occasionally for Drawing Attention, the group's e-zine.
