So, a friend and I were out in Loudoun County, Virginia this weekend on a mixed-surface/gravel route that we got from a local bike shop. A few miles in, we are on a wooded two-track about a quarter mile off the main road and this pickup truck rolls up on us (somewhat aggressively) to tell us it's a private road and we need to turn around. We hadn't noticed any signs on the way in, but politely thanked him for letting us know and follows him back out to the main road to reroute.
When we got out there, we found this tiny blue and white sign with nothing to the effect of "do not enter" or "no trespassing" or even "closed to the public." It simply said "private road, not publicly maintained" in small lettering. That road was only 1.5 miles of a 35 mile route, but we ended up on several more "private" roads, most with much more prominent and specific signage. All told, probably close to half the route. And we did pass other cyclists on several of them.
So I wanted to see if anyone on here knows if this kind of private road in Virginia is actually closed to the public, or if this guy was just flexing on some out of towners for kicks. Didn't find much useful info on the state or county websites when I checked. Where I moved here from (Montana), if a road had a proper road sign and wasn't gated off, it was almost always fair game regardless of whether it was publicly owned/maintained. Heck, some fire roads were gated off and still open to public travel (just watch out for cattle on the road).
