I'll try section 416 stairwell again. But it shouldn't be this hard to find a good variety. There should be IPAs, ESBs, and/or porter/stoudts at every 4th beer stand in Nationals Park. I hope Stan Kasten will get the message.
Actually the situation seemed to have improved at Monday's match - the 'Base Line Brews' on the 300/400 concourse near the stairwell to 416/417 still had its Pilsner Urquell supply going in the fourth inning (albeit with rather a lot of foam)...baby steps, I guess. The other one further clockwise along that concourse (Bass and Stella draughts) looked like it was going fairly well at mid-match too.
