Imagine how many jobs that could be created to shovel up the horse schite that will be put down by the stock required to replace our current transport system, and the saddle and harness makers, hay and fodder suppliers, horse trough makers and installers, nose bag makers, grooming brush and comb makers, smithies and farriers, stable lads and lassies, etc. etc. Zzzzzz. Back to the future covered in it instead of talking it.
