Hey Evenflow, congratulations on acceptance! I have an aunt and uncle that live in Mesa and have lived there for the past 30 odd years. They love it out there and my parents usually head out there during the winter to visit them. The only things I really know about AZ is from a retiree's perspective - golf courses, warm/hot weather, pools, and MLB Spring Training...
However, there has been one thing that my parents both ended up getting the last time they went out to AZ - San Joaquin fever/coccidiomycosis/valley fever. The main symptoms are a nasty dry cough, fatigue and headaches. Also, it typically lasts for about 3 months at a crack... Just thought I'd mention it.
