That's not Rams or Goats or anything like that; it's actually Goat Heads. If you live in the south/southwest, you know what goatheads are. They are basically seeds from some kind of ubiquitous wild plant that are great at sticking to you, giving your bike flat tires, and poking you whenever you touch them or try to pull them off. The logo script very much suggests the spines on goathead seeds.
