Be sure to mark your calendars for the Grayslake Historical Society’s annual living history tour of the Grayslake Cemetery. Visit the cemetery on Lake Street, just north of Belvidere Road on Sunday, October 4 at 1:30 or 2:30 for a fascinating program given by costumed actors. This year, the tour will feature business people from the turn of the century, including a druggist, boat builder, dry goods merchant and hardware store proprietor.
