When I was still out west, and a lil younger and not so smart, I met an old man that was wearing just one spur as he was riding his horse. I thought ,at the time, that was strange. So I asked him why he only had one spur on. He kinda looked at me and said "That's all I need. I found out long time ago that if I get one side of my horse to go in a certain direction, the other side would follow". There was nothing I could say.
