I have been here for 20 years and only have two complaints: too hot in the summer and too many people moviing here
Phoenix is now the 5th biggest city in the country and we continue to grow at about +8,000 people per month net in migration......
we have the usual big city problems (traffic, crime, etc) but not as bad as other cities our size (although we are #1 in auto theft because of our proximity to Mexico)
we have 8 months of glorious weather and 4 months of uncomfortable (very hot) weather.....but, you don't have to shovel sunshine and just about every home has a pool!
In the summer, you can drive 150 miles and be in 7,000' mountains to cool off in AZ or drive 360 miles and go jump in the ocean in San Diego (San Diego's population doubles in the summer because of us "Zonies")
housing is relatively inexpensive, although if you live in certain parts of town it can be as expensive as you want...I believe the overall cost of living in Phoenix is about at the US average
two race tracks within 50 miles of any place within the metro area (which is huge.....about 30 miles by 30 miles I would guess)
Generally, AZ is business friendly, union unfriendly, Republican controlled legislature, and conservative. Relatively low taxes, but rising slowly but surely.
Right now we have the highest priced gas in the country because we continue to use MTBE and nobody else does......(our highest pump octane is oxygenated 91....)
It is not the best place in the country to live, but it is certainly in the top 10
