Stravaiging again

Before the final stage of the Tour de France, an antuquey potter. When I was small, you could send off a few shillings for a tiny model engine, just for the pleasure of hearing it go vroom and congratulating yourself for going up a step from Meccano. Me, I hung on to my shillings.

This, on the other hand, is big enough to drive a motorbike. For all I know it still goes vroom. And now it's on a brand new wheelbarrow sort of thing. The question is why???
