Maps are cool. Here in Maine, everyone owns DeLorme's Maine Atlas & Gazetteer. In fact, everyone keeps one in each vehicle. It's just the way of things.
Jack used maps. Hell, he even drew maps. This one details his hitchhiking trip in 1947-48, which was of course partial fodder for On The Road.
Get a map. Use a map. Draw a map.
Maps mean travel. Go go go!
