A little warmth was in the air, and with it, the Noah-sized stream in the backwoods was in free-flowing form. Just after lunch, I did a five-miler, at an aerobic pace and without a camera to tempt me to slow down, so I didn't have much time for a natural history walk. But my son's namesake stream is only about one hundred yards or so from the house, and that's where I headed. The water was noisy, and in many places, the current manufactured bubbles of every size. This one was especially pretty, with its mass of sunstars. I didn't see this at the time, but if you look carefully at the bubble's bottom area, you just might notice that your humble documentarian has put in a cameo appearance.
