It’s Homecoming Weekend at both the University of Maine and Husson University, so there’s lots going on for the next three days in both Bangor and Orono. Elsewhere, in Bangor improv comedy troupe The Focus Group does its last show at the soon-to-close Bangor Arts Exchange at 8 p.m. Friday. For Halloween fun, Maniac Manor in the Bangor Mall is open all weekend, and for little ghoulies, United Cerebral Palsy hosts Pumpkins in the Park again at 11 a.m. Sunday at the Anah Shrine Temple on Broadway. And in Waldo County, it’s the 19th annual Belfast Poetry Festival, which has lots of neat community poetry events, including a Haiku Death Match at 7 p.m. at the Colonial Theatre in Belfast.
