I saw a lot of birds this trip - four green herons (they would get puffed up when I came close, then squawk their discontent and fly away), three blue herons (one of which was absolutely huge, like a dinosaur flying ahead of me down the river, a few hundred yards at a time), two hawks, six kingfishers, three turkeys and a couple of mature Canada geese with two juveniles.
A little over a mile and a half up river, the stream became so choked with debris that I couldn't easily portage around it. It also seemed to become dry enough that I might have done more dragging and carrying than paddling, so I called it and headed back. We've had a very dry year, so much of what is normally accessible by boat, isn't right now.
Under the train bridge, I found a water spider about 3 1/2 - 4 inches across. It was a big'n!
