The 22nd annual Southbury Celebration community event scheduled for October 9th has been cancelled.  The family event is cosponsored by the town and Southbury Training School.  First Selectman Jeff Manville says the day typically attracts thousands of people, including kids who aren’t able to be vaccinated against COVID-19.  While COVID cases in Southbury are leveling off, town officials don't want to risk a spread in the schools.
