What a great day, no wind, so I headed to the local Lake to drown a few worms, as usual another big Donut. Anyway who wants to fish when you can watch a Black Swan attack a dog. People walking there dog decided to let it off leach about 40 feet from where I was fishing I didn't say anything, I think they thought it was a big joke until this black swan that looked pi$$ed off headed towards the dog flapping its wings and started to attack it. The people with the dog started yelling and trying to hit the swan with the dog lead, the more they carried on the more the swan hunted the dog. Finally the dog exited the water. I have never seen an angry swan before. Later I was told the swans had a nest close by.
