S.D.
We live in Peoria as well but I would say the northern part of Peoria is a good place to be for long term. Scottsdale is expensive and Paradise Valley, but both beautiful areas to live in and a lot of golf resorts and such there. Chandler is well known as a good place for a young family. I have not heard much about Mesa to live there......but Tempe is very much for college. Surprise, Estrella Mtn and Good Year are also affordable areas. When you do head to the southern part of Peoria , I'd say Good Year and Surprise may have better schools . I just don't know much about public schools at all here. I avoid them and send my kids to private . But a lot of my friends have loved their public schools . Oasis, Oakwood, Fronteir. to name a few.
We find tons of things to do.....but it is hot and so most of it is in air condition buildings for entertainment. It is an adjustment if your not use to be in a/c all the time.
Kristy named quite a bit of stuff to do......so I would second that.
If you could get into a meet-up group, moms group or something like that, I would really encourage that as you begin your journey here not knowing anyone. A lot of moms groups have disolved for lack of people...but meet up groups, stroller strides is a group I think......
Good luck. Contact me if you had other specific questions. There is just a lot on this subject to really write it all down. :0)
You will love the winters that is for sure !
