This is Sun City AZ, which is basically a retirement community for boomers. There's a church in the middle of each of those circles. They also have a bunch of boomers called the Sun City Posse that ride around looking for people to profile. These guys used to wear branded M-a-r-i-copa County Sheriff uniforms, and rode in vehicles that were also branded for the longest time. One of the more bizarre places I've spent time looking up on the internet.
