when I was a kid ridding on the milk cart the horse opened up it exhaust and boy I will never for get that sight as I was right behind it and the smell made all us kids sick , I think it was revenge of the horse as there were about 6 kids ridding on that milk cart and the horse was a cleaver one he stopped at every house the farmer wanted to deliver to then walked onto the next one , Land Rover was 7years old by then.
