The bus route you *have* to ride is...

• The 5A or the B30, even though you're not flying out of those airports.

• A rush-hour only route to the MD or VA. Getting back might be a challenge, though...

• The 7M - Mark Center-Pentagon Line, since it's one of the newest routes in the system.

• Something obscure, like the 8Z - Foxchase-Seminary Valley Line

• It doesn't matter. Just be sure to ride the entire route, from start to finish.

• Any of the high school buses. Just be sure to pack noise-canceling headphones!
