I gave myself a guideline a while ago: if I love something, get involved with it. The only sport I watch is Formula 1. It's not really possible to get involved within the US Midwest. But, there is kart racing about an hour from me, and I go there every month or so for some fun. So, I get to race fun little carts, and I can enjoy F1 more. If I lived near a real racetrack, I'd volunteer marshal, because it'd be fun to do.
