I lived in NM for 16 years, and always meant to go down to the Organ Mts. I had Unganade's book. Alas and alack. I still have friends in Las Cruces, maybe a visit is in order...
Yes, the Las Cruces area has tons of wonderful outdoor activities. It is, however, not at all well documented in print or on the web, so it takes a little bit of exploring! C'mon down!
