I have not heard of Fontana Lakes, but if you want a great place to retire in Arizona consider Prescott or Prescott Valley, about 1 1/2 hours north of Phoenix. It has been listed in magazines as one of the best places in Arizona for retirees. Mild climate, clean clear air, and always something going on in the community. It's a great place to live. Please contact me if you are interested. Thank you!
