Lukeville-Why (85) ~25 miles. map pic1 pic2 Very scenic two-lane road in Organ Pipe NM. Southern Arizona is the place to go if you want to see the 'stick-em-up' cacti. However, If that's your thing the pros know that the best sights are not in either this or the Saguaro parks but rather north of Tucson on route 77, roughly from Oracle to Winkelman. pic3
Speeding in Arizona is extremely risky because of heavy border patrols looking out for drug/people smugglers. Be good though and you'll be enjoying one of the most scenic places in America. pic4
