I have been living in Chandler for the past 8 years or so.
Honestly, I would not choose to live anywhere else. I have lived in several different cities (Pittsburgh, Dayton, Las Vegas) and this is the first place that truly felt like HOME from the first day we moved here.
I'd classify it as a "professional younger couples with kids" type of area. Lots of great places to work nearby (Intel, Motorola, Boeing, Wells Fargo). There are huge parks everywhere, lots of classes through the city for the whole family, close enough to ASU and that scene, light rail to all of Phoenix right there, and now - thanks to the economy - some really cheap housing (comparatively speaking I guess). Bargains abound though.
Four casinos within 20 minutes, two with some great poker rooms (Casino Arizona and Gila River).
Nationally ranked high school football in our backyard (Hamilton High School).
A lot of the area is very clean and new. The downtown area is dingy but undergoing a revival of sorts as the city dumps money into redoing the whole area (which is very small to begin with).
5 minutes to Gilbert (another great area).
10 minutes to Tempe, Mesa, and Ahwataukee (sp).
25 minutes to the airport
30 minutes to downtown Phoenix with no traffic
4-4.5 hours to Vegas
4 hours to Mexico
6 hours to LA and San Diego
Flagstaff an easy 3 hour drive up the mountain to escape the heat in the summer for a weekend.
Lake Pleasant and several others places to boat.
Salt River Tubing fun to drink and tube for an afternoon.
Obviously I could go on and on.
Where are you coming from? What are you into? How old? etc... I can answer anything you'd like about the area.
