Why, AZ is a small rural community in Pima County, Arizona. It is due north of Organ Pipe Cactus National Monument in Southern Arizona and lies near the western border of the Tohono O'Odham Indian Reservation. Why is approximately thirty miles north of the Mexican border where Lukeville, Arizona and Sonoita, Sonora, Mexico border each other, and ten miles south of Ajo, Arizona.

The name of the town originates from the original Y intersection of State Highways Route 85 and 86. At the time of its naming, Arizona law required all city names to have at least three letters, so the town's founders named the town "Why" as opposed to simply calling it "Y." The Arizona Department of Transportation (ADOT) later removed the old Y-intersection for traffic safety reasons and built the two highways in a conventional T-intersection south of the original intersection.

James and Peggy Kater moved to Why, AZ in 1949. They built a pub, restaurant, store and post office. Water was brought in from Ajo, but as more people came, a well was developed with federal funds. Electricity was also brought in around this time.

During this time, many older folks parked their trailers at what is now a highway rest area. Many of them hoped to stay in Why permanently. But the county health department, noting the lack of sanitary facilities, decided the campers must go. So, some permanent residents of Why applied to the Bureau of Land Management for 122 acres for a trailer court and campground. They got a special dispensation from the health department if a park could be installed in 30 days.

Almost everyone pitched in and in 30 days, the park was ready. It included roads, restrooms and hot water for showers. Virgil Denning provided heavy machinery, others the labor. The water-lines were dug by women and children. Those too old to do heavy labor cooked stew and chili beans for workers. The park was named "Coyote Howls."

Eventually the people who came to cherish Why joined together to build a community center. The community center is active throughout the winter season with activities to appeal to everyone. During the summer season many of the residents move out due to the high temparatures.

In the summer of 2002, Why Utility purchased Las Palmas RV Park and renamed it Coyote Howls West. It is near the original campground on Hwy 85 in Why and features full RV hook-ups. Campers can now enjoy the camping experiences provided by both the East and West park.
