Monroe: Named after the president, it's home to the Evergreen State Fair and the Monroe Corrections Center (so behave!). The Ring and its sequel were filmed here. And there's a bunch of geocaches.
The details about the daylong sunrise-to-sunset cache machine (start time 5:15 a.m. on June 22) are in this forum discussion, but the official event is this after-machine dinner.
Dinner will be at the Route 2 Taproom, 19837 US-2, N 47° 51.552 W 121° 57.912. Be there at 7:30 p.m. on Saturday, June 22, 2019. It should run about two hours.
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!
A "will attend" note here will be greatly appreciated in order to help plan dinner arrangements.
