In the spirit of Robb’s hobby of picking up hobbies, I took scuba diving lessons (well, that and I managed to get the lessons for $50 instead of about $300.) I just finished the second of the pool sessions, which leaves only the open water dives. So far it is a lot of fun, but another expensive hobby is probably not in the budget long term. If you where ever interested, the lessons are a lot of fun, and worth the time. And you can check off one more thing to do before you die.
