A few weeks ago I did a little experiment while shooting in PDX. I stood on one of the short brick walls surrounding Pioneer Square and let the Leica hang around my belt buckle. I prefocused in a general area on the sidewalk and snapped blindly as a wide variety of people walked by. I liked the results and plan to try it again in a different part of town. I'm debating on leaving some kind of sign on the ground and catch reactions when they see it. Something like "beautiful" or "barf" or "why not" or something, I don't know, a decision for another day.
