My mum in the 1920s or if the babe is me, early 30s, as I am one of 7 children so I wouldnt take a bet on it. I do think the Thames on a punt is pure bliss and I spent a lot of time on them in the 50s when I was supposed to be in art school and was lucky enough to have later lived in a barge "Lord Churchill" on the river in the 60s
