indicates the U.S. population will be majority-minority by mid-century
Well that’s a bizarre way of phrasing that.
In fairness…
There are tons of “National Historic Sites” that are falling into disrepair or just flat being sold off beyond these.
Hell, every few months my Dad and Brother get both physical and email mailers about how another corner of the Gettysburg Battlefield was bulldozed to make a new strip mall, where I lived in North Carolina, one of the fields of a skirmish that was relatively important to the surrender of Jefferson Davis is literally a Wal*Mart.
and then there are the sites that are part of a larger site. Like the Motel mentioned… The people I know travel Route 66 to see ROUTE 66 (not to mention much of Route 66 itself has disappeared), they’re more interested in the Cadillacs that are upended and buried along the roadside then a “Historical Motel” (of which there are more than a few)
Historical sites are lost all the time. It has more to do with public indifference to Historical Sites in general than it does to the history there.
