This sign is located on highway 75 in New Mexico as you enter it from highway 518 in the San Juan Mountains. The GPS coordinates for it are N36 10 37.7 W105 37 15.7. See sign on map!

Ed.: This is the fifth sign from New Mexico, which now has more mathematically significant road signs than any other state (Nebraska is in 2nd with four!). Put your state on the map by sending in a mathematically significant road sign! Remember, the first sign from a state is also given a First in State gold star!
