Here's the problem: You need to transport yourself and your goat, but all you have is a bike, and it doesn't even have a little basket on the front. Also, this is no petting zoo pygmy goat, this is a full sized, adult goat.
Of course, if the goat would cling to you like a backpack, all of your problems would be solved. For some reason, this goat is very agreeable, and will indeed cling to this guy like a backpack. Maybe the goat is actually in charge here, and is using its hooves on the man's collar bones to direct him.
