"The community supports this so well that we are starting to attract people from other areas," Muller said. "We are unique, and while we are used to it up here, it intrigues others."
The Mason-Dixon line divides the northern tip of the Appalachian Blue Ridge Mountain Range between Pennsylvania and Maryland, but up on the mountain, the line is blurred by the friendships of those who live here.
"We are one mountain," said Jeff Coyle, chairman of the Heritage Day Committee.
Standing side by side, Coyle, who lives in Maryland, and Muller, who lives in Pennsylvania, said they might live in different states, but they are residents of the same community.
The inaugural car show attracted 42 automobile owners from the Tri-State area.
Many owners, such as Tammy Fraley and her husband, Rich, came to show their vehicles somewhere they never had shown them before.
"This is great," Tammy Fraley said. "It is nice to come out with friends and look at the cars, but when it is for a good cause, it is even better."
Two groups were raising money at the festival -- the One Mountain Foundation and its partner, the Cascade Sons of the American Legion.
For three years, the Legion has raffled a Harley-Davidson motorcycle to benefit the Fisher House, a foundation that provides lodging for families of wounded soldiers near military hospitals.
This year, Post Commander Wayne Schrader said the Legion was raffling two 2008 motorcycles with the hope of raising $20,000 for the Fisher House.
The money raised by the foundation through vendor fees, donations, an auction and the car show will stay on the mountain through donations to local schools, Boy and Girl Scout programs and civic organizations, Muller said.
Mountain Top Heritage Days continues next weekend at Fort Ritchie in Cascade with historical lectures, tours, a scavenger hunt and fireworks.
