First time I towed a caravan, I thought "There doesn't seem to be so many on the road as it usually see!". Then I realised why..........because of the restricted speed, all the caravans go at the same speed, you never have to overtake one !
So (all you miserable hits in Wales and the West,), if all those caravans annoy you, go out and buy one, and they all disappear.......
Genius, eh ?
