"Enter if you dare," it warns.

Bollschweiler's haunted home at 1152 Stratford in Sugar House began as small-scale project in 1991 and has evolved into a major yearly production. Her house has been rewired to provide special electric outlets for decorating and currently has eight outdoor timers.

Her yard display includes witches, bats and a graveyard, along with mechanical spiders, ghosts and skeletons. The Grim Reaper, Phantom of the Opera, Batman, Darth Vader and The Mask, some of the costumes of Halloweens past, are assembled on the porch. Mummies clad in San Francisco 49ers and Green Bay Packers jerseys hang on opposite corners of the house. They symbolize the rivalry that exists between Bollschweiler and her housemate, Betty Ovard, during football season.

The pumpkin patch, however, is the crown jewel. There are 57 made of foam, each of which took two- to eight hours to carve into likenesses of everything from Frankenstein to the Headless Horseman, Merlin to Medusa and Shrek to Yoda. Bollschweiler's favorite is the Grim Reaper. Part of her tradition includes a gathering of friends the Saturday before Halloween to help carve another 10- to 20 fresh pumpkins to add to the yard.

Bollschweiler decorates because she is "just a kid at heart," but she is also motivated by the enjoyment it provides, particularly to the many elderly people who live in the nearby condominiums. Neighbors have donated props and helped string lights. Because space was getting scarce, Laura and Kendal Powell, who live in the house to the east, consented to display the luminarias in their side yard.

"I like it because I don't have to decorate so much myself," Kendal Powell says.

Four-year-old Charlie Fields, who lives nearby, had no complaints.

"It's fun," said Field, who was visiting Bollschweiler's yard for the fourth time.

Indeed, Bollschweiler's home has become a favorite haunt for many Halloween fans. People come from as far away as West Valley City and Bountiful to see this spectacle, and it was featured a few years ago on a local TV news channel.

Bollschweiler dresses up herself as well as her home. Her past Halloween costumes have included a dinosaur, a bag of French fries, an M&M, Ms. Pac-Man and a mummy. This year she will dress as a spider and expects to welcome some 150 trick-or-treaters.

Ovard may call her "Halloween-obsessed," but Bollschweiler has no plans to let go of her obsession.

"I do it because I enjoy it, and I'm going to continue decorating for as long as I can," she says.

After she spends the requisite 30 hours tearing everything down and putting it away, she'll be ready to start planning next year's extravaganza.
