Breeches is a bum strap on a driving harness./QUOTE]
Technically, the term is Breeching, because it is only one strap. Never have heard it called breeches by any Driving folks. Must be a local thing again.
My vocabulary is expanding with this discussion!
I now will know what breeches are when heard in relation to a harnessed driving animal. I knew breeching on the harness, though the rump strap has also been referred to as britching, britchin, by various folks who drive or use pack animals, ride mules.
