Apparently, there's an organization called Stitch'N'Pitch that arranges for knitters, crocheters and crafters alike to attend baseball games and sit in their own special section, where they can enjoy the game and work on their respective projects.
They recently attended a San Francisco Giants' game - I think it's an awesome way to get all the crafters from one area together to meet one another. Not only that, but Stitch'N'Pitch is also a charity organization that finds needle mentors and gives them the resources to teach crafting to kids.

You think they'll ever come to a Yankees game?
