First there was "You can't get there from here", that phrase that country folk love to trot out when a hapless out-of-stater got hopelessly lost in Maine and had to resort asking the natives for the directions. Or so the out-of-staters said.
Then there was the AAA Trip-tik: the set of mini-maps where the friendly AAA representative highlighted the route you were to take to get from A to B. Depending on the trip, you could end up lugging a small library back to your car, of the Trip-tik itself, plus the maps and the AAA guides that went with it. For a cross-country trip we're talking the weight of a small encyclopedia.
Then - oh marvel! - there was the GPS device that was built in or (more commonly) precariously attached to your windshield with a suction cup. Super-expensive versions told you the real-time route, accounting for any detours due to road contructions of traffic jams.
But all that is so twentieth century.
