> Commute into a DC metro based office once a month

Not even once. Have you ever driven in DC metro? No thanks.

From Cumberland, you can take the Amtrak. It's a 3 1/2 hour ride, you can eat on the train, and there's no traffic.

$38 for a round-trip ticket.

The Marc drops you off in the DC Metro (the subway).

Which on first reading I thought you were referring to with "DC metro," and I got very confused.
