It seems that cows have free reign in the Azores. We came across a cow that was standing in the middle of the highway because it wanted to eat the grass that was growing on the side of the road. This bull was not tied to anything, and could easily have charged us, but it was just eating grass while it looked at the waves breaking on the cobblestone beach.
The bull seemed pretty calm and relaxed, but I would still not recommend grabbing this bull by the horns!
