Hi Frenchie -
I had posted the same question on this site several months ago with no response at all. I'm in Miami and I have yet to see anyone else sketching in public, so I'm excited to see your post. My schedule is a bit busy right now, but maybe one day next month we can get together if you are interested. E-mail me at firstname.lastname@example.org
if you'd like. My blog is at http://danscanvas.blogspot.com
if you want to see what I do.
