Every March (and late February) is exciting, because everyone is getting ready, or getting healthy, and the new players are coming in. There are a ton of new storylines, and optimism is on high. I'm also more likely to have tickets during the season than in October. I keep posting stories, because I'm getting pretty excited about this season.
October isn't always exciting, sometimes the team is out of it, and you generally already know who the players are, and how they're going to play. And football is always a huuuge distraction from baseball.
