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 7:00 PM on Saturday, March 18, 2017 at Rancho Viejo, 170 S Grand Ave, Pullman. The coordinates are listed above. I expect we'll end around 9:00 PM.
Please log a "will attend" as soon as you know you'll be there. I'd like to give the restaurant an idea of how many of us will be there before we all show up.
Be sure to put this on your watch list now, so you'll be among the first to know about changes and updates as the big day approaches!
