I did think of one thing - fantasy baseball. It's a hobby I enjoy, and in the past I've flown to California every Spring for the annual draft. I was in a league with the same friends there for 7 years, and it was something my wife understood was going to happen when we got married. However, now that we're about to have our second child, flying to CA every Spring does seem a bit frivilous, so I've agreed to join a local league next season. I'll find other ways to stay in contact with my friends in CA.
