Or if you mean that you're driving through fields to visit a neighbor (during favorable seasons and no recent rain) rather than take roads, doesn't opening and closing all the gates in the fences slow you down?
Yes. Including the bridges which was done diy, lol. I have all my own road maintenance heavy equipment and fix the roads if they get bad. And yes i mean a real road network. Basically my entire 'town' is private road easements without any government or even HOA/ psuedogovernment administering them, there are not gates to open or close.
>Does the USPS have no issue with delivering mail via private property?
USPS won't come here. UPS and FedEx does though. I have no government mail service.
Kids can get to a school via bus but you would have to park at the interface between private roads and the nearest public road. Bus won't drive on our private road network. You can get to some schools 100% by private roads, depends on which one.
There are fleets of vehicles I'm aware of that rarely, if ever, hit tax payer funded public roads or rail.
These fleets include graders, dozers, rollers, et al for private road maintenance.
These are real, your skepticism is understandable but not applicable.
In parallel with private vehicles on private roads there are also public roads upon which school buses travel (assuming kids don't just off-road it to school on a motorcycle or, still today, a horse).
