It was a beautiful morning but I immediately dead ended into a tree that had fallen in the channel on the north side of Island Dock. Why dead ended?

I rowed out on the Hudson to Red Nun 74 to enjoy the wonderful breezes the Hudson provides and was curious about the little tower I can see from the beach when I am there. So I rowed to it. There were at least two osprey nests on top and the inhabitants were very distressed with my visit. Then turned on my NK to find out how far I had traveled. When I hit home port I double the meters.
