You've seen them as you drive along, those "Adopt-A-Highway" signs, usually featuring the name of a local anti-litter philanthropist.
But even jaded motorists will do a double take at the name emblazoned on several signs near the entrance to the Lost Dutchman State Park. Instead of bearing the names of the sponsoring do-gooders, these signs merely declare: "In loving memory of John Denver."
So why the Arizona tribute? Seems it's part of some fans' efforts to get John Denver Adopt-A-Highway signs -- and roadside cleanups -- in all 50 states.
