The 878 prefix serving Fort Ritchie, Md. seems to be reachable in three area codes: 301 in Md., 202 in DC area, and 717 in Pa. 878 shows up in Baltimore directory as "Fort Ritchie (Baltimore City service)" and in DC area directories as "Silver Spring". I assume area code 202 goes away for this exchange next year. As for 717, I had seen 878 listed as Blue Ridge Summit (717-794 prefix), and was wondering where 878 was used until I visited the area earlier this year and realized I was right next door to Fort Ritchie when I was there. (A pay phone near the gate to Fort Ritchie is on 301-241 in Highfield, Md.)
