I wonder if you used (or if you feel that it would be useful) surface entries 
on these roads/paths that are being mapped.  I know I added some surface 
entries when I was mapping parts of Columbia based on what I was seeing.  I 
suspect a road classified as a primary route but is also dirt, or otherwise 
not paved, would make a difference in calculating route times and knowing what 
kind of vehicle would be best to send.
