From Exit 16 off of US Interstate Highway 40 (Westbound) turn right on Historic Highway 66 and NM State Road 118. Just as road narrows
to one lane, find Mentmore Drive. Head north (turn right) and maintain course to dirt road, passing bike-and-hike trailhead, and past designated police range. Stay on course. Locked gate on right will indicate the range, as will signage.
