It's great to know that I'm not the only one bothered by all these berting signs.
I guess I've been chomping away at actual signs for only a few years, but mostly I've been removing fliers from lampposts and other public places since <i>at least</i> high school.
I mainly patrol the Northside and the inner ring NW suburbs, but have chomped a few on St. Paul's "Rocking East Side" and around the U of M - Twin Cities.
