I've been cooking (black bean and sweet potato burritos, from Moosewood Low-Fat Favorites) and listening to the National's home opener on the radio.
I actually prefer radio to TV for baseball, unless I've got someone to watch with and chat with during the slow bits. By myself, I'll turn on the TV, then pick up a book between innings, and forget about the game. But listening to the ballgame on the radio is perfect for cooking, or gardening, anything that keeps the hands busy but leaves the mind free.
I'm excited to have a team in town. Oh, I'll always have a soft spot for the Mets, the team I grew up with. (I was a fan when they were awful during the early 80s, and was rewarded with that marvelous couldn't be believed 1986 postseason.) But it's hard to be a baseball fan without listening to or watching the games on a regular basis; you don't know the players, their strengths, weaknesses and quirks, whether they're hot lately, if they've choked in the clutch... And a good bit of the joy of being a fan is being part of a community, being able to say "did you see that hit last night?" and expecting the answer to be yes.
My husband isn't interested in baseball at all, and the boys are too young to really follow the game. But I'm working on them. I figure they should be ready for their first major league game right around when the new stadium is built.
