I have purchased quite a bit on line from Wyoming Outdoor Industries.
They have lots of blaze orange stuff - including hobbles - figure 8 as
well as three legged hobbles. I will say here that the blaze orange
biothane hobbles ARE wonderful for a hobble broke horse, but not for the
training process. They also sell all kind of camp and packing supplies.
