Historian and author Thea Lewis guides inquisitive minds ages 10 and up around Burlington’s most compelling haunts during Queen City Ghostwalk’s Darkness Falls Tour. The perennial outdoor crowd-pleaser — and recent Daysies award winner — spotlights some of the area’s lesser-known history: From chilling theater specters to gruesome serial killers, Lewis leads listeners on an unforgettable journey through spine-tingling days of yore. Although encounters with ghoulies, ghosties and long-legged beasties aren’t guaranteed, previous guests have reported witnessing strange phenomena during the spooky stroll. But as Lewis reminds us, “Ghosts are like people — they can be moody [and] unpredictable.”
