[Tagging] surface=gravel problems

[Michael Patrick]

 I wish someone in the world had come up with some sort of simple
systematic method of rapid observation via visual and touch by an
individual of the salient factors for passability classification of both
road segments and routes, suitable for global use from the equator to the
Arctic Circle.
Hmmm ... maybe the Chapter 5, Technical Reconnaissance – Route
Classification of the  U.S. Army / US Marine Corps Engineer
Reconnaissance manual
?
