My personal bucket list changes, but my top ones right now are places I have not been already and my opinions are based on those of dancer who have attended these as well as videos: Canadian Swing Championships looks like a fun party (someone mentioned an open bar), I love the track choices and energy of Inspiration Weekend, and have not tried out for The Balboa Experiment yet (is that how that works?).
So, where would you go, and why? I'd love to hear about your favorites, too, if you just want to say why you would go back to an event. Maybe I'll add some more to my short list.
