The government shutdown closed the museum, and they thought that might shutter plans to spook crowds this weekend.
Because it's on private property owned by the Museum of Aviation Foundation, they're able to open as planned.
Here's the top five reasons the Nevermore Hills Haunted Trail promises thrills and chills.
1. A creepy old house, built in the 1800s.
Organizer Nicole Bissette said, "It's actually very spooky in and of itself."
They don't know the history, although there's spine-chilling rumors that add to the trail's mistique.
2. A tree supposedly used for hangings during the Civil War.
Accounts about the tree's history was confirmed with a museum historian while Bissette and her partner Jenny Maas planned the event.
Pointingto the tree, Bissette said, "This actual branch here was the hanging tree for union soldiers."
The brave souls that wander through could encounter their ghosts, they say.
If not, they may mistakeactors for the real thing.
3.One hundredthirtyactors along the trail; A minimum of 40 each night.
Maas said, "They're amazing. Were giving them the freedom to do what they want and improvise to make up their own stories."
4. An unmarked grave site.
The trail winds around the crumbling headstones, that are bordered by an ornate iron frame.
Bissette said, "We've left it untouched, just out of respect."
Knowing they exist lets the imagination run wild, which isn't hard to do in the woods.
Maas said, "Being in the woods alone, just that feeling."
"That feeling would be number five on the list, if it weren't for the ghastly prospect that jumped out Thursday night.
5. The trail was almost cancelled the day before it opened
The government shutdowns' ax swung the doors of the museum shut Thursday night. After six months of work, that shook organizers to their boots.
Maas said, "We were on pins and needles for a little bit."
It all worked out, with the trail opening at sundown Friday night.
It costs $13 per person to tour the trail.
The proceeds benefit the Museum of Aviation and the Aviation Hall of Fame.
