Count me in as someone who thinks graffiti is a big problem. (“61% of Portland voters call graffiti ‘big’ problem, poll from The Oregonian/OregonLive finds,” Oct. 23) I take umbrage to those who deface our city. The public square is not your canvas. To summarize my feelings about graffiti, I’m reminded of the old saying: Fools’ names, like fools’ faces, are often seen in public places. If taggers only knew.
