Maybe 20 years ago, my partner and I packed out a medium sized bull 4 miles in 1 trip with a standard, garden variety wheelbarrow. Granted, it was on a logging road and 95% downhill. The short uphill sections got old very fast, though. A couple years later, I tried it myself with a spike. I discovered that you don't want a cheap K-Mart type wheelbarrow for that. It collapsed and is still up there, hidden in a brushy draw.
