I totally concur with Mr. Trainguy regarding Baranca del Cobre. Been there during '75; it is specular, and no highway goes near it. To my knowledge, there is a "landing strip" that can handle a small aircraft the size of a Cessna 402 (of Cape Air varietal, Mr. Trainguy and that I once flew BOS-ACK), or if it still runs, the "Chepe" over the Chihuahua Pacific.
Although, I've never ridden it, no highway is near the Silverton. They have gates, I understand, that block the ROW, including an access road.
