Filthy stoker swopping aplenty was had yesterday on the YACF southern tandem ride
Graham and Jonathan were borrowing Margaret Hilda anyway (Mr Whippy keeps breaking spokes). I captained Jonathan and Emma. Joth and Emma (Things 1 & 2) then had a go on the Santana.
I think at one point we decided that we'd exhausted the permutations of who rides on which bike, given height, pedal systems and so forth.
Joth even wore my shoes to ride the Santana. He said that they were "still warm" and "nice and moist"
