There's no testing needed. I'm a Pirates fan first and always will be. I watched games in Forbes Field with my dad many years ago. That's where my love for baseball started and it will always have roots there. Simple as that.
If you were true to your moniker, you would understand about really enjoying baseball and enjoying watching it wherever you can. I'd go to Astros games if I lived in Houston and cheer for the home team unless the Bucs were in town.
I just don't appreciate others teams fans talking smack about the Nats fans' loyalty after spending six effin hours in the cold with about 30k fans.
We joke a lot about the Fan Police around here but who are you to judge how fans should behave at the park? If people want to leave early because they have other obligations, so what? It doesn't make you a better fan for staying.
