I was returning from an assignment. It was longer than planned and my C300 batteries were completely drained out. When I was passing by the side of a lake, I saw this view. The local sewage treatment plant had discharged untreated water into the lake and the resulting foam had completely covered the water. It was looking like ice. I did a quick shoot with my Go Pro Hero 4 Black on a Steadicam curve to highlight the issue. Henceforth, even for casual travel I am carrying the Go Pro 4.
