Link Bridge Pano
I took this shot on Lake Shore Drive during the Bike the Drive event, looking west from the middle joint on the Link Bridge over the Chicago River.
One foot was on each movable leaf of the bridge while bicyclists passed in both directions behind me. Even with considerably less mass with bikes than the cars usually passing, I could feel the leaves each independently rocking up and down from the shifting weight.
