Gen X and prior used a lot of landmarks to get from A to B where routes were commonly used. Landmark navigation is still heavily used today in places like India and Mexico where routes change hourly sometimes due to road closures and accidents that gps mapping cannot account for.

I once had to drive pre-google from Paris, France to Madrid, Spain and then to Valencia, Spain with nothing more than a AAA Auto Club map and a Philips Road Atlas. Not fun in many eays, but it was an adventure.
