At a white Victorian-era home in Anoka, one of its former residents, Col. Paul Giddings, who died in 1930, is said to keep an eye on the place to this day.
The current homeowner believes that the colonel's ghost led her to the furnace room in the basement one night, where she detected a gas smell, according to Darlene Bearl, a volunteer docent for the Anoka County Historical Society's ghost tours.
"If the homeowner hadn't called [the gas company] on it when she did, the family would've succumbed to carbon monoxide poisoning or the furnace would've exploded," Bearl said.
The house is just one stop on the historical society's "Ghosts of Anoka" tour, which begins its ninth season May 17. Blending storytelling with colorful facts, the tour recounts all kinds of "unexplained" occurrences.
It's based on countless testimonies that the historical society has gathered through the years, Bearl said.
Starting at Anoka's history center, a costumed tour guide takes people in and around the downtown area to a number of historic homes and city landmarks, including the pistol-shaped City Hall, the armory, Colonial House, Main Street shops and Billy's Bar and Grill (formerly the Jackson Hotel), among other places.
The walking tour is filled with anecdotes about such mysterious events as piano music that plays out of nowhere, cigar smoke that can be smelled without a source, blue mist and flashing lights that seem to have no point of origin.
At one house on the fashionable 3rd Avenue, where "anybody who was anybody" once lived, there's a ghost who, it's believed, doesn't like people to wear shoes in the house.
