okay, this is nowhere near as serious as the kinds of stuff that miulang posts but it's been bugging me. you've seen old people with walkers on the sidewalks, right? well, a lot of people seem to use those green/yellow tennis balls on the back two of the four legs. not sure why. maybe cuz they slide easy enough but still provide enough friction so it doesn't go slipping.
anyway, my question is, "is this a hawaii thing or is it fairly common to see on the mainland, too?" thanks.
