I read your post with interest. My 88 year old mother lives in a nice condominium near an upscale market. She used to walk the half mile to the market, but she can't any longer. So she uses a cab. She does use a walker now to get around. As an aside, it's been my observation that women are much more determined then men to walk.I live in my single level house, (though it also has a walk out finished lower level since it is sited on a sloping lot).By car, the local supermarket is 1.1 miles from my house. Though I'm perfectly capable of walking that distance, (even though its hilly), I choose not to. I could argue that the lack of sidewalks makes the walk more difficult, but I know that is an excuse.It helps me though to observe that no one else walks to the market either!
