Driving through the Santa Fe area yesterday, I noticed an NM 300 route marker just north of I-25 exit 290. That route was previously in the HB, but I removed it as unsigned before activating usanm. Now that it's signed at least at its east end (apparently not at its west end at NM 466, and I don't know about signage mid-route), I'll add it back to the HB once I'm back home in a few weeks.
Also, on NM 599 in Santa Fe and US 84/285 north of Santa Fe, there are a few interchanges with new exit numbers not in the HB. I'll have to plug in those exit numbers along with the NM 300 addition.
Not a change, but an amusing note: on US 84 in eastern New Mexico (and US 60, concurrent at that location), there is a county road waypoint labeled CRAP.
