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: Pier Restaurant & Grill, 715 Simundon Drive, Point Roberts, WA. Be there at 7:00 p.m. on Saturday, September 27, 2014.
If you could let me know in your "will attend" log below how many adults and kids you have, that'll really help in getting me a head count for the restaurant.
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!
