COLUMBUS, Ohio (AP) -- More than 35 million Americans are expected to travel by car this Fourth of July, and a good chunk will probably reach for technology before they unfold -- or try to refold -- a paper road map.
Transportation agencies around the country have noticed, and are printing fewer maps to cut costs or just to acknowledge that public demand is down.
But amid the boom in affordable GPS devices and built-in navigation on smartphones, there's nostalgia for paper road maps.
At a recent collectors' association exposition, hundreds of old road maps were on sale to give customers a glimpse into an era of romanticized advertising promising sunny Florida or Chicago's famous skyline.
Mapping experts believe there's incredible potential in the industry as more people want to know where they're going.
