The one goat clearly has a leash on. While backpacking in the Sierra Ancha once, I encountered 8 of these animals, 1 giant white dog larger than Blanco, and two leather clad folks living in a teepee.
Their goats looked just like these. These folks said they moved around every month or so and hit all the NF's throughout the year. Each goat carried 50-60 lbs of gear. The guy told me he had just lost two goats in the Supes to lions. This was their transport and re-supply depot. [ photo ]
They were quiet neighbors for two nights and I offered them 2 extra trout I had caught, which they accepted. None of their goats were aggressive, just nosey.
