For those who don't have a Garmin and would like to do the Coops Sawmill courses with a smartphone, I have posted Clint's event file at UsynligO. I tested this facility this morning on the Brown course and the UsynligO app on my iPhone 12 Pro worked perfectly. I got the "you're at the right control" at every control, including Start and Finish, when I got within about 12 - 15 meters of the streamer Jim & Rich hung. My sensitivity was set to 15 meters.
This should be a tribute to Clint for precise georeferencing as well as his accurate mapping.
Coops Sawmill is a very attractive venue. Thank you, Clint, for bringing us to it.
I paused between #4 and #5 to photograph this waterfall:
