Against his better judgement, my husband agreed to drive from Silver City to Interstate 25, using New Mexico Highway 152. That highway is in excellent condition, but is probably the curviest, most challenging road that we have ever taken. The canyons are steep and some of the sides do not have barricades or retainers to prevent cars from going over the edge in the event of a sudden flat tire or a skid. We loved the scenery, which was beyond our expectations, but do not plan to drive on that highway again.
