I think this is the right answer. A road ROW is typically just that - a right-of-way for the road + uses associated with the road (maintenance, pulling over for emergencies, etc.). You can't have a tea party on the ROW just because it's a public ROW. If you get dropped off and don't park, you might be OK. On the other hand if the ROW is limited to certain purposes, your access might not be as clean as it seems. Not sure how it would all play out, but I don't think it's quite as clear as one might think.Soooo take this for a grain of salt, but just because a road has a public right away easement or a road easement doesn't necessarily allow the public to use the area the paved or improved road surface.
Best way to find out, call the local road department that has the jurisdiction of that road, which also means that right away and ask them. The right away could be public to a certain point then be a utility easement, which most of the time you don't have access to.
Easements and rightaways are still a gray area, something I'm learning working with a public entity. Just do your due diligence and not go off of what a forum says.
