Thanks for the heads up. I know most of the land owners over there so I think, we should be good to go. Just FYI, the road is no private. It’s a public road.
It’s a public easement across private land. That's a really common thing in the mountains, but it isn't usually in such a populated area. Just be polite & don't tear things up, as most of 68J residents on the west side of the reservoir have, "Had it up to here" with Boulder traffic/campers/shooting and are organized & already talking with both the county & the forest service about new rules to put in place. And honestly they are good at it.
The waypoint you guys are talking about is just the corner of Magnolia & 68J. It is well signed, and the paddock right there usually has Alpacas in it. Also if you come up Magnolia to get there, keep an eye out for Yaks in the fields!
