The City of Batavia will observe Halloween activities from 5 to 9 p.m. on Oct. 31st only. Police Chief Shawn Heubusch reminds trick-or-treaters to use caution when crossing any street; always use a clearly marked crosswalk; and look both ways before entering the crosswalk. Younger trick-or-treaters should always be accompanied by an adult. Be safe and have a Happy Halloween!
