Class B Road Maintenance, An Approach For NM?

In executing the necessary rethinking of transportation in New Mexico, here is a possibility.

Iowa has what it calls Class B maintenance. This was what the sign said on the entrance to a "road" (trail, really) outside a small south Iowa community east of Interstate 25. A gate barred entrance to the road. We didn't check to see if the gate could be opened. The sign cautioned drivers that they entered at their own risk.

The road offered plenty of weeds.

The difference with New Mexico is that the Iowa approach explicitly people informs what isn't happening, namely maintenance. New Mexico neither maintains roads, nor tells anyone.
