I have friends that live in Arizona (none in Green Valley Arizona) and have heard many good things about the place. The make-up of Green Valley Arizona in nearly 100% white (96.6%); very affluent, with low unemployment. My friend (from Phoenix) says its one of the best places to visit in the state (although it is mainly a retirement community).
With golf courses (about 10 within short driving distance, no pun intended) , shopping plazas, clubs, volunteer organizations, medical facilities (seven hospital or medical centers) , places of worship (of all religions) and recreation centers (8 major and 3 more close by), it's hard not to find something to do there. If you're looking for a great place to visit (or even live) in Arizona; give Green Valley Arizona a good look.
Located just south of Tuscon, Green Valley is within driving distance of some great attractions; it is also not far from the Mexican border (Nogales) if you are inclined to visit there.
