Public transportation between DC and Baltimore

[stockjock]

I'll be heading to DC for a wedding the weekend of Memorial Day. We are staying in DC and won't have a rental car. On Friday night I'll be heading to the Orioles game.

I'm pretty sure that I can take the train from Union Station to downtown Baltimore on the Camden line to get there. However, it doesn't look like the train comes back into DC when they game would be over. What are my other options besides an expensive cab ride?

Thanks in advance.

I did that Memorial Day 2 years ago. After the game, there were free buses operating from the Camden rail station (right outside the ballpark) back to Union Station in DC.

Edit: here's a link with more info. Buy a round-trip MARC ticket for $14 and it will include the bus ride back. Buses leave 20 mins after the last out.

Wow, that's just what I was looking for. That should work for me. Thanks!
