@ cobrad - Our experience has not been positive with Llamas. Three of them got spooked when they saw our goats and their owner (with an open umbrella) about a hundred yards off, they (Llamas) turned and ran off...didn't stop for 14 miles. I know some folks love them, but we have had bad experiences with them.

I have owned packgoats for 7 years and use them every summer in rugged conditions. My first two were worthless (from a dairy breeder), but my current six, from a reputable packgoat breeder in Oregon, have been priceless. Mine carry anywhere from 40 to 60 lbs each, depending on the terrain.
