Under cloudy skies, on Friday the 13th, groups of the curious took half-hour tours Friday into the unlucky history of downtown Warren.

Warren County Historical Society’s annual Haunted House and Trolley Tour kicked off Friday night.

The horse-drawn trolley made six tours Friday, each starting and ending at the historical society and including a stretch along the Allegheny River.

Local volunteers Gary Lester and Ron Keeney told the curious tales associated with sites along the way.
