Ghost on the road

I've never had the opportunity to drive it, but the shortcut to El Paso from Laredo is claimed to have ghosts. I think it's US90, runs through Marfa and Alpine Tx. I used to get to Laredo quite a bit, and got to know some of the TexMex drivers for the company. These guys would tell ghost stories about that route. They had me shivering with goose bumps more than once.
