Have you seen the Nationals play at their new stadium in Washington, D.C.? It's gorgeous and a lot of fun.  You can have dinner at Ben's Chili Bowl or Five Guys, and enjoy a nice cold beverage, all the while watching the nation's past time with a friend.  Stay the night at the Hotel Palomar Washington D.C.  The next day you can have a nice breakfast and then take in the sights around D.C.
