Climate control is most of it. I'm from this area (although I haven't been to Metcalf South in ages). Our winters are mostly below freezing and our summers are mostly above 95, so for older people, walking outside is rather less appealing than walking in what amounts to a climate controlled indoor track. Sadly, this isn't even the worst case. The (not so) Great Mall of the (not so) Great Plains in Olathe (about 20 mins away), actually opens early in the morning so people can use it to walk. The stores don't open until 9 or 10, but the mall itself will open at 7 for walkers. This mall is a giant oval that is probably 3/4 of a mile in circumference, with carpeted floors. Yeah, it's stupid, and it's not that cold/hot outside, but honestly anything is better than the average suburban exercise routine, which is to do nothing.
