**This one snuck up on me but I still wanted to post it for those who have never been.**
You can purchase your tickets through the TVBWF website http://www.tvbwf.com/. Your rsvp here will *not* get you tickets to the 3-day event.
Recommended photo opportunities are the Balloon Glow, Balloon launch, and Tethered Flight. There are also ample opportunities for food/drink and event photography due to the number of performances and vendors attending.
If you go, please leave a comment with the date and approximate time range you're attending so other Meetup members can seek you out.
