Residents are expected to participate in nightly security checks. Residents of the West End and Common House use a calendar to assign each unit a week of nightly walk throughs. Around 9:00 PM, please check to confirm that doors and windows are latched and locked, and look for anything out of order. Common House residents check the ground floor of the Common House. West End residents check the Common House basement. East End residents use a looser more informal system without a calendar. (Bob Cowherd 2018)
