WASHINGTON 鈥 Most months of the year, the campus at the , a nonprofit school dedicated to educating and supporting children with disabilities, is calm and peaceful.
But come October, things get a little weird.
It鈥檚 not unusual to find a gallon of 鈥減rofessional quality blood paint鈥 on the desk of facilities director Matt Smith. And Lisa Kimball, chief executive officer of the Arc of Loudoun, is used to answering emails in her office to the sound of bloodcurdling screams echoing down the hallway.
The stench of fuel in the fall breeze? 鈥淭hey鈥檙e just testing out the chain saws,鈥 a staff member explained. There鈥檚 an equally casual explanation for the smell of mildew inside the property鈥檚 abandoned 19th century mansion: it鈥檚 a special diffuser designed to set the scene 鈥 a scene of pure terror.
That鈥檚 because in October, the Arc of Loudoun transforms into one of the region鈥檚 largest and scariest Halloween destinations for its annual event.
鈥淒uring the day, we鈥檙e all really hard working,鈥 said Kendra McDonald, director of clinical services at the Arc of Loudoun.
鈥淵ou might stop in at the Aurora School and see Katie Loudermilk working on testing with some of our students, and then a couple of hours later, it鈥檚 dark and you don鈥檛 want to be anywhere near her.鈥

Come sundown, Loudermilk layers on make up lacerations, changes into a bloodstained apron and goes by 鈥淢awmaw,鈥 one of the creepy characters hiding inside the dark mansion.
The Arc of Loudoun provides one-on-one support (sometimes two-on-one support) to students with intellectual and developmental disabilities, and to help pay for the quality of care administered, it often turns to fundraising.
Nine years ago, the school realized the best way to bring in the dough wasn鈥檛 with bake sales. Instead, staff decided to cook up a terrifying experience inside Paxton Manor, the 150-year-old mansion on campus that Kimball describes as an estate 鈥渋n need of massive renovation and restoration.鈥
鈥淏ut in the meantime, the gift of it is it鈥檚 also kind of creepy and scary,鈥 said Kimball, who added that paranormal investigators have detected activity inside the mansion.
Over the years, the monthlong haunted house has turned into a yearlong effort. Smith, whose unofficial school title is 鈥渉aunt master,鈥 attends conferences to check out the latest trends in the industry and to track down the scariest products. He plans the details of each room鈥檚 design and storyline well in advance.
鈥淭he attention to detail is second to none,鈥 Kimball said. 鈥淚t鈥檚 a PG-13 level experience.鈥
More than 80 volunteer actors (many of whom are students in Loudoun County Public Schools) attend 鈥済houl school鈥 to fine-tune their scare tactics, and more than 500 volunteers work to make sure the thousands of visitors enjoy 鈥 or at least make it through 鈥 the experience.
Last year鈥檚 Shocktober attracted 12,000 people and raised more than $400,000. Kimball predicts this year will be even bigger.
Shocktober is open every Friday, Saturday and Sunday from Oct. 5 through Nov. 4. Tickets are $35 online/$40 at the door and include entry into three levels of Paxton Manor, plus its basement, Carnival of Souls. Concessions, including beer from Old Ox Brewery and wine from Tarara, are available for purchase. More information is available on the .
