A rather useful thing was invented in the USA. How do you make sure that history is preserved for centuries? Books burn, the internet is obviously a temporary phenomenon. Across the entire US territory stand these signs called Historical Markers. There are already over 220,000 of them. They are practically indestructible — these are raised letters on a thick metal plate. Often there’s a quite wordy paragraph on them, and they are placed not only in recreational areas but often in places where you can neither drive up to them nor easily walk up. For example, you’re driving on a highway where you can’t go under 40 miles per hour, and there’s nowhere to stop, and somewhere off the road in the field there’s a marker for deer about some battle. Well, apparently, they believe that when they will be needed, there won’t be a problem in accessing them.
