^ I had a similar mental image, only involving walkers rather than canes (and I have three school-age kids too) and it was that aspect specifically that bothered me...it just sounds maybe a little too close for comfort to 'Dress Up Like A Handicapped Person Day', and that I would definitely find objectionable. I don't know, I've seen isolated individual kids dressed up as 'old people' for Halloween and wasn't bothered by it, so maybe it wouldn't make sense to have a problem with this. And you're probably right that some grandparents would get a kick out of it...
