At Nats Park you can take food in with you. Not sure why anyone drops serious coin and time at a game to get crappy ballpark food.
Absolutely. I understand getting ballpark food every once in a while, and for some a beer at the park is pretty much a ritual, but I'd rather bring my own sandwich, peanuts, and water bottle to the game. Great for your health, wallet, and hey, less trash.
I also hate standing in those lines, and last time I got something there was no more onions or ketchup. If I get ballpark food I want condiments on it, thanks.
Also I have never had a problem with kids at the park. At the Yankee's game on Friday I sat behind and beside two very young boys with their fathers. They were quiet, inquisitive, and seemed pretty interested in the game considering their ages. Neither of them needed endless bathroom breaks or concessions to keep them happy. I remember going to a few Expos games with my dad as a youngin' and wouldn't want to deprive that experience from any decent, well behaved kid, and even the not so well behaved.
Nats Park is pretty good in my opinion (good fans, nice view) when I don't eat ballpark food.
