My dad, brother, and I are headed to DC for his Navy ship's reunion. 3 days are pretty much full but we will have 3 evenings (after 4) to do whatever. Going to tour Annapolis, the Navy Ship Yard, Arlington, and a river boat cruise. Any dining, entertainment recs in and around the city? I've been to DC twice and have done the monuments, museums deal but will probably head to the Lincoln Memorial.
