This is kind of crazy and something I did not know.
A limestone mine and government paperwork.
“In BOYERS, Pa. — The trucks full of paperwork come every day, turning off a country road north of Pittsburgh and descending through a gateway into the earth. Underground.
It processes federal employee's retirement paperwork.
“They have 28,000 file cabinets, full of paper,”
The file cabinets full of paper and the massive amounts of space they require are necessary because the system hasn’t changed since the 1970s.
There have been at least three attempts to digitize the process since the 1980s but they were ultimately unsuccessful. 😳
