* If you end up heading towards Tucson on I-10, near Demming is a hidden gem of a campground, Rockhound State Park. It's fun hunting for geodes, but they are hard to find. It's easier to find reasonably priced samples at the rock shop just outside of the park. Look for the little shack with piles of rocks and lots of solar panels along side the road a couple miles before getting to the park entrance. http://www.emnrd.state.nm.us/PRD/Rockhound.htm
* Valley of Fires Recreation Area (near Corrizozo, north of Alamagordo on US 380). Great campground with water, electric and showers; but it may be hot this time of year. http://www.blm.gov/nm/st/en/prog/rec..._of_fires.html
* Mesilla, NM (suburb of south Las Cruces). This little Mexican village has interesting shops, a town square with old Spanish mission church and great Mexican food at reasonable prices. Most people don't know about this little hidden gem. http://www.oldmesilla.org/html/getting_here.html
