RE: the map thingie that gets handed out when you enter a park or NM etc
For Glen Canyon NRA I have a copy from 2004 and a copy from 2017
They are nice looking "maps" with features of interest and roads etc.
For some reason, the NEWER 2017 version removed all the internal road numbers for Glen Canyon NRA !!
There is a trend to in some agencies-departments to make maps that look pretty - and not worry about content (or lack thereof). It pisses me off no end.
