When out in the hinterlands, a highline is handy hardware for keeping a horseman's herd hitched for the night. A highline is a horizontal rope, tied to two trees or other immovable objects, with rings for securing the animals by lead rope and halter. Highlines are not much hassle to hang, and the system keeps horses happy and safe.
Horses can rest there, hang their heads to sleep, or have a bite of hay if they're hungry.
We hang bells around the horses' necks so we can harken to the harmonics while we sleep. The sounds are hushed if they are calm but become loud and jangling if they're harassed or hyper, and we can hasten to check and see if they are hurt.
On cool nights at high altitude, they wear their stylin' homemade blankets (above).
If we are on a pack trip and regular blankets are too heavy to haul, they can wear space blankets for body heat. (In the photo, we have these emergency blankets secured with leg wraps and duct tape. How's that for haphazard innovation? No matter, our horses are habitually in style, a haberdasher's envy.
