I didn't see any of them. Kofa got its name from the King of Arizona mine, which is in the refuge. I bought a box of dates at this date farm in the Bard Valley on the California side of the Colorado River. The date farmer and I talked about workmen's compensation and rodents for a while. I told him I was out taking pictures of lizards and snakes, and he told me how much he likes gopher snakes.
Rodents eat dates.
Gopher snakes eat rodents. Farmer sells dates. Farmer likes gopher snakes. The box of dates held 15 pounds, and they are highly delicious. I was proud that my only checked luggage when I flew back to San Francisco was a big box of dates.
