At the risk of being teased to counting down my birthday (which I haven't done since I was 10), I'm wondering...what should I do to celebrate?

Melissa found a cheap/fun cruise, but I can't get that much time off of work (a week).

Mary Ann has suggested a glass bowing workshop that will also have the bonus of working in a visit to St. Louis.

I've always wanted to go ski diving.
