Back when there was sun and warmth there were a lot of these tridems going up and down outside. Somehow people look optimistic on them. This trio waved to me and cried ‘hello!’ as they wobbled past on there newly rented wheels. I betray both my age and background when I say that my first and probably only association upon seeing them is The Goodies. As I saw tridems passing me that day I kept mentally hearing ‘Goodies Goody Goody Gum Drops!’ I would be surprised if anyone else here had that song rattling through their head.
