Wow, I thought it was steeper than that! 3 mile hill over Tuscarora Mountain (Route 30, Fulton County. Nicknamed McConnellsburg mountain, for the town I live in) is 14% and is a main truck route for truckers avoiding the toll on PA76. There's been several times I've been behind a semi and start smelling something. Sure enough you start seeing smoke and they're burning up the brakes. Coming up the mountain you'll see a semi on the side of the road and it's just a smoke show. Out of towners, lol.
