Wednesday was a busy day on campus. The "Free Speech Zone", which usually hosts only the Bible ladies and an occasional salesman or two, was the venue for a political-religious group with huge, provocative posters, handing out flyers to passersby. According to reports in the school paper, some past demonstrations have led to shouting matches, but as far as I could tell, nobody got loud on this day. The campus police were posted a few yards from the edge of the zone, just in case.
