I have watched the Orioles and Nats on MASN and MASN2 for years in the Baltimre/Washington area. I recently bought a house at Deep Creeek Lake MD and had Comcast installed. Where is MASN and MASN2 in the channel lineup? Are there any Orioles/Nats fans in western MD?
You're in Garrett County, MD. That's part of the Pittsburgh television market.
DirecTV and Dish both offer MASN and NBC Sports Washington, but Comcast in Accident (the system you're likely on) and Grantsville only offer AT&T SportsNet Pittsburgh. Shentel for Oakland does not offer any RSNs, they dropped AT&T SportsNet Pittsburgh last year.
Beginning in Allegany County, the Frostburg, MD/Keyser, WV system has MASN and MASN2, as well as Atlantic Broadband in Cumberland.
