Even taking the Acela round-trip to BWI is cheaper than the mileage and parking at the airport when I lived in Houston, or when I lived in Atlanta and was still driving to the airport.
I've been know to take the Acela to BWI from time to time when I haven't felt like waiting for the Regional, or on the way back from BWI if the Acela was the first train to come through. IIRC it's about $30 with advance purchase, $35-ish for walk-up, one-way.
