My parents hit their snow saturation point last week and would like to escape the north for a month or so. They are somewhat familiar with Phoenix and Tucson, because I used to live there, but they would like to go somewhere that they can get around for groceries and other basics without a car. They do not desire any activities other than a nice place to walk and sit outside and get some sunshine. Peace and quiet are ranked much higher than things to do. Any ideas?
