Last week in Pargess Burk, er, Burgess Park, I saw a woman on a big tricycle with a large box trailer affair between its front wheels. There were 4 sprogs of about 4-7 years old in it, clearly having a great time. As she passed I noticed a 5th sprog in a shoulder carrier on her back.
Battersea Park regularly has fair numbers of Jewish parents wheeling one or two sprogs around in box trikes, but this 4 seater was considerably bigger. Easily big enough to accommodate one of my portable drum kits....
