Just to be clear, I'm talking about hiking trails. Forest roads in the
area have already been uploaded with the TIGER import (at least the ones I
know of).
On the hiking trails themselves, labeling is very inconsistent. Typically
they're labeled with common names (e.g.. Three Rivers Trail No. 44), but
occasionally they're labeled with a 'T' prefix (e.g. T5004). Most forest
service maps just list the number, e.g. 44, or 5004.
Based on various USFS docs, for roads in the USFS system I'm using:
For Forest Highways (generally major paved roads): ref=FH nn (e.g.
name=Angeles Crest Highway + ref=FH 61).
For Forest Roads/Routes/Truck Trails: ref=FR yDxx (e.g. name=Upper Monroe
Road + ref=FR 2N16)
For Forest Trails: ref=FT yDxx (e.g. name=Heaton Flat Trail + ref=FT 8W16)
