Spotted...

that brompton rider, as you subtly put it, happen to be my missus' mother actually! she hasn't ridden a bicycle for 15 years (she's used to fixed gear bike back in South America) we decided to put her inbetween us in order to keep her safe.

Ha ha, sorry mate, no offence intended. To be fair she was riding a Brompton, so my description was purely factual. I figured she was with you guys. First time I've really seen your Jackson in the metal - very nice.
