If this isn't yet relevant, then I've stumbled across secret information and it will be very relevant very soon. O. Roy Chalk had a varied life and you can look him up to find out more about him, but I'm thinking the most relevant part of his life is within the following paragraph. He purchased the Washington, D.C.<https://en.wikipedia.org/wiki/Washington,_D.C.> transit system on August 15, 1956, for $13.5 million, renaming it DC Transit<https://en.wikipedia.org/wiki/DC_Transit>. Chalk owned the Georgetown Car Barn in Washington, D.C., adjacent to the famous steps where the part of "The Exorcist"<https://en.wikipedia.org/wiki/The_Exorcist_(film)> was filmed. The building was a streetcar shop erected in 1895 that supported the Capital Transit Company<https://en.wikipedia.org/wiki/Capital_Transit_Company> system, which circulated through the District of Columbia. By Public Law 389, enacted by the United States Congress, Chalk was directed to replace all streetcar operations with buses, which was completed on January 28, 1962. On January 14, 1973 WMATA condemned DC Transit and its sister company, the Washington, Virginia and Maryland Coach Company and acquired their assets for $38.2 million. He retained ownership of the Georgetown Car Barn, however, which had been converted into office space between 1957 and 1960. Chalk owned the building until 1992.
