Wisconsin, Michigan, Ohio, Kentucky, Indiana, Illinois and Home - September, 2012
A Foucault pendulum set up to knock markers over at occasional intervals. Quite a crowd had built up next to this marker waiting for it to go down. I snapped this right before it went over, but it looks like rather than the pendulum pushing it over, it "twanged" it on the return to center. September 28, 2012@14:45
