'Contrail' - or how to re-claim the streets with the aid of some coloured chalks

yeah nice, so if someone sees you riding along and links the colour up with your bike and you, they follow the trail like goldilocks and theyve got your house, your pretty bike and your pretty chalk dispenser.

Goldilocks didn't follow the trail, that would be Hansel & Gretel.
Fairy story fail.
