lmao I feel your black booger pain!! ;)
At least our current horse isn't much for rolling. He tends to stay on one side or the other. But, he loves to try to grind it into his face. That is the reason for the fly mask 24/7 in order to limit eye infections.
Our first horse had a really long mane and tail and went for the dreadlock look in his hair. I sometime would get to the point, so I could ride after spending over an hour grooming him, that I would just clean up where his tack would touch and pick his feet. I always felt guilty after doing that, but there were times it would take me over 2 hours to get him stripped of all mud. What a piggy he was.
