I was near the end of a hike this spring when I saw two pit-bulls coming up the trail. This is an area that requires dogs to be on leash. They acted very aggressive and I stepped off the trail and picked up a short stick to use as a club and continued down the trail. They turned and ran back to their owner. When he came up he chuckled and said "I hope my dogs did not scare you!" I said "If you do not want to scare people then do not let your pit-bulls run loose!"

Him: "They are friendly and would not hurt anyone."

Me: "Yes, but I was preparing to hurt them."

I turned and walked away, but he seems disappointed that I was worried about hurting his dogs rather and vice versa.
