Well, don't assume they'll speak to them. Sounds like an old map from a previous tourist visit, am willing to bet.

IF wanting to keep that road open to what sounds like some awesome camping etc, I think the USFS would welcome your suggestion, and I think it's also a sign they'd put up to spare themselves some grief later on.

A thought; your first paragraph alone makes this place sound like it's worth fighting for to maintain public use don't you think?

Democracy is two wolves and a lamb voting on what to have for dinner. Liberty is a well-armed lamb contesting the vote.
