20A

Quarter to eleven and still needed to blip... took my camera: batteries die. Looking for fresh ones; didn't find them. So I took my other camera, but when I switched it on the low battery life-indicator already flashed: I managed to get one shot of... that's right, the pile of empty batteries that I had collected in abovementioned events, before those batteries died too. So now I have 10 AA batteries and they're all empty...
At least they proved to be a blipable subject.
