The details about the daylong sunrise-to-sunset cache machine are in this forum discussion, but the official event is the after-machine dinner.
Dinner will be at the above coordinates: Puerto Vallarta, 8208 NE State Highway 104, Kingston. Be there at 4:30 PM on Saturday, December 28, 2013.
Please log a "will attend" as soon as you know you'll be there. The restaurant can handle at least 50 people, but I'd like to give them a better idea of how many of us there will be before we all get there.
Be sure to put this on your watch list now, so you'll be the first to know about changes and updates as the big day approaches!
