More about horses

In Sweden, everybody knows how to tie the horses. They "must" be parallel, but opposite - like this:

(well, they can be the other way around,too)

Either tie one shaft to both ends of one horse, the other horse to the two other shafts (works best, IMO), or tie both horses to the middle shaft.
