We are considering going to Washington DC for the 4th next week. How busy/touristy is it that day? We live 6 hours away, but we'd basically only be there that day. I know we could do the Nats game, museums, concerts.

I'm also going to be 33 weeks pregnant, so I'm not sure if it's the greatest idea (I also don't want to take the extra day off work since I'm budgeting what I get).
