I grew up in Phoenix and unless you are living near what you want to do it's got to be challenging to have no car. Where I lived, behind Thunderbird park, it's pretty built out, but it's still 3 miles to any store. When I was a kid, before they built 101 and then some stuff further north, it was five or six miles to anything.
You must not discount the heat on a summer afternoon. It can be miserable.
