Drive through the Lower San Pedro River Valley, and a well-graded dirt road will take you past homes, organic farms, ranches and other structures where fewer than 200 people live. The only other signs of human presence are a handful of lesser dirt roads and an underground natural-gas power line.
They coexist with prickly pear, agave, saguaro and other cacti, and Sonoran desert trees and shrubs. Cows graze on leased, state-owned or Pima County-owned property.
Now this tranquil valley is the final battleground in a decade-old conflict over a two-state power line.
