Vancouver (not BC), Clark County (not Nevada), Washington (not DC): It's 29 years older than its Canadian counterpart, 307 miles further south, and chock full of caches. The first Vancouver (WA) Cache Machine was 10 years ago. It's time to go back.
The details about the daylong sunrise-to-sunset cache machine (start time 5:15 a.m. on June 23) are in this forum discussion, but the official event is this after-machine dinner.
Dinner will be at Sweet Tomatoes, 12601 SE 2nd Circle, Vancouver, (N 45° 37.224, W 122° 32.507). Be there at 7:30 p.m. on Saturday, June 23, 2018. 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.
