When I sat here, the Nationals were taking on the Marlins which is far from the best team to see playing the Nationals. Those Orioles series are always fun.
Although 310 isn't behind home plate, it practically overlooks it so the view isn't all that different than when you sit in section 313 or 314. The view of the infield is great without too much being taken from the outfield.
The sight lines are great at this stadium but something is missing here and you pick up on it after you have visited so many other ballparks.
Nationals Park itself was interesting with all of it's high tech visuals on the scoreboards but the layout of it left me pretty cold. There wasn't the nostalgic feel that Camden Yards in Baltimore has. What's a shame is the Orioles lost a lot of fans when DC was awarded a franchise.
