The Colville Chamber of Commerce advertises "Discover our good nature! ... Come to visit us and enjoy our small town hospitality... where outdoor recreation is literally at your doorstep." That means geocaches, right?
The details about the daylong sunrise-to-sunset cache machine (start time 6:30 a.m. on September 22) are in this forum discussion, but the official event is this after-machine dinner.
Dinner will be at South Main Restaurant and Sports Bar, 993 S. Main Street, Colville (N 48° 32.088 W 117° 54.288). Be there at 7:00 p.m. on Saturday, September 22, 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.
