That has the potential of having the county engineer explain "No, it is
not a private road." Some people around here hang private road signs as
a bluff.

It's most certainly a private road, but, the police were called by a biker
who refused to turn back who said I accosted him and knocked him off his
bike (I never touched him or his bike).

The police said that their maps don't show it as private, but, that it is
marked private only at the entrance and that in order for them to arrest
someone, we need to sign it according to California Penal Code 602L, which
basically says we need signs at the entrance and exit and along the borders
and along the road at a density of at least 3 per mile.

(L) Entering any lands under cultivation or enclosed by fence,
belonging to, or occupied by, another, or entering upon uncultivated
or unenclosed lands where signs forbidding trespass are displayed at
intervals not less than three to the mile along all exterior
boundaries and at all roads and trails entering the lands without the
written permission of the owner of the land, the owner's agent, or
the person in lawful possession, and any of the following:
(1) Refusing or failing to leave the lands immediately upon being
requested by the owner of the land, the owner's agent, or by the
person in lawful possession to leave the lands.
(2) Tearing down, mutilating, or destroying any sign, signboard,
or notice forbidding trespass or hunting on the lands.
(3) Removing, injuring, unlocking, or tampering with any lock on
any gate on or leading into the lands.
(4) Discharging any firearm.


It seems that 602N may also apply:
(n) Driving any vehicle, as defined in Section 670 of the Vehicle
Code, upon real property belonging to, or lawfully occupied by,
another and known not to be open to the general public, without the
consent of the owner, the owner's agent, or the person in lawful
possession. This subdivision does not apply to any person described
in Section 22350 of the Business and Professions Code who is making a
lawful service of process, provided that upon exiting the vehicle,
the person proceeds immediately to attempt the service of process,
and leaves immediately upon completing the service of process or upon
the request of the owner, the owner's agent, or the person in lawful
possession.
