Sasco has always been private property. I was out there just today doing some site cleanup. I didn't see any new signs or any sign of LEOs. If they've been out there, I imagine it's because people have been causing problems for the nearby ranchers/neighbors. Doesn't mean LEOs won't be out there on weekends, since that's when it gets used the most, but I haven't heard anything to that effect.
As a heads up, the water was fairly high today. I took a dirt bike out there and just about swamped it.
From what I understand, as long as we're not being disruptive or destructive, and there are no signs stating the area is private property, we can use the area within reason. However, if asked to leave, we've obviously got to comply.
