Give me a museum and I'll fill it. (Picasso) Give me a forum ...
We have an indoor mall in the town I retired to. Whenever someone comments in a neighborhood group about the mall, stores coming or going etc., some people always have to chime in with their “indoor malls are relics”, etc. It annoys the heck out of me. At a minimum indoor malls are excellent climate controlled places for people with mobility challenges to get some exercise.
Our big mall (Ala Moana) is more out-door than indoor. Also, it remains so busy that I don't think it would be a good place for exercise walking. Too many people coming and going. Large as it's parking garage is, certain times of the year, parking is really difficult. I can't think of the last time we went there. Probably only to go to our Olive Garden, maybe back in March? The mall has been there more than 50 years and it keeps updating - especially to lure tourists. It would surprise me if it's not still there in another 50 years, but YMMV.
We do have other malls and you could walk there just as we used to do on the mainland at our local mall. Here, we just go outside to walk, more or less 365 days/year. We just have to plan when the sun will be behind trees or buildings. Once in a while we have to dodge rain. Otherwise, "where" to walk is just a matter of today's whim.
