Goats! Very Ingenious! I think the concept is Fantastic!
But it's not really "Backpacking" is it? I think it is fantastic but you have a Train of Pack Animals here to carry the better part of your Camp and load for you right?
Bugout, I was fortunate enough to do a trip with goats exactly once. They belong to a friend, not me. Every other year, it's a backpack for me.
But you're right, it is ingenious, and I'd do it again in a heartbeat.
