8 minute exposure with about 10 flashes around the cab. Half way though the exposure the calmness of the night changed very quickly and the wind started gusting hard. I thought for sure it would shake my camera blurring the picture, but the little cheap aluminum tripod held its ground and only the trees blurred from their erratic shaking. I wasn't sure what to expect from that, but I like it. It seems to give the picture movment, as if the haunted truck is knocking the trees aside as it drives though while hunting down its next victim. If only I would have lit up that headlight . . .
