Boo On Main is this Saturday with treat stops from more than 50 participating organizations and thousands of little ghosts and goblins expected to join in the fun. Organizers ask for cooperation in helping lines form smoothly and be patient with fellow guests at this fun, family event. Officials also ask that attendees use one of the two entrances to access the event area. The north entrance, starting at Town Center Park, and the south entrance, beginning at Cumberland Valley National Bank. Guests will have the chance to follow the treat loop and exit from the same end they entered. By the way, Trick-or-Treat across London-Laurel County will be on Halloween, October 31, 5:30 p.m. to 8:30 p.m. Special thanks to all city departments, including the London Police Department, London Fire Department, Public Works, and Laurel County Department of Public Safety/Emergency Management, for partnering with London Tourism & Parks to help make this event happen.
