Bruce Olson got a kick out of scaring trick-or-treaters in San Francisco by jumping out of a pine box coffin he built and set up in the yard.
When the family moved to Minnesota in 2005, he continued the tradition — and went even bigger.
The Olson Haunted House fills the family's three-car garage and spills out into a labyrinth through their Chanhassen yard. There are hay bales, coffins, an electric chair and an assortment of spooky characters. Of course, as in horror movies, some of them wield chainsaws.
The Halloween tradition is now in its 16th year, drawing thrill seekers from near and far for the frightening affair at 2432 Lake Lucy Road. Olson's wife, Holly, and sons Anders, Mac and Parker, help pull it off.
"When we moved here, we weren't so sure whether it would be as big," Anders Olson, 20, said. "But slowly and slowly it grew."
Admission is free, but the family gathers donations for charity. Proceeds from this year's haunted house, which is open from 6:30 p.m. to 11 p.m. on Saturday and Halloween, will go to Special Olympics Minnesota. Cash donations are welcome or people can fill out an online form at the door.
Last year, about 755 people steeled their nerves and passed through the haunted garage, bringing in more than $1,000 in donations for the nonprofit Loaves and Fishes.
This year, the Olsons are expecting even more people. They have enlisted 18 volunteers to act in different scenes and tend to visitors. They've added new acts over the years, including a ghoulish funeral scene, an evil dentist scene and a clown room.
