Last January 2013, the Trentonian (a New Jersey newspaper) posted the following photo on their Facebook page.
Frozen Delaware River
It is really unusual to see that much ice on the Delaware River so I headed over to photograph it myself. There were a number of people standing on the dike/retaining wall who were photographing the river with cell phones and small digital cameras, but I went to the far side of the bridge which was the sunny side. A Port Authority Guard stopped me and said there is a Homeland Security law which prohibits photographs of bridges and other structures. He said I could stand on the retaining wall and take photos of the water but couldn't include the bridge. Grrr....
So I decided to photograph the shadow that the bridge cast onto the frozen water.

The shadow is the Trenton Makes Bridge from the Pennsylvania side of the Delaware River. These were taken on January 26, 2013 with my D90.
And below is the top of the retaining wall upon which I am standing. Although the retaining wall doesn't look too high, it is
at least a 15-20 foot drop to the water/ice below.
On February 3, 2013, I went to the Bristol Waterfront Park and photographed more ice chunks that came up on shore. This photo was shot at 70mm so the ice blocks are compressed in size. They were
much larger than they appear here (actually about 15" to 18" in diameter) which is one of the disadvantages when shooting with a telephoto lens. I wanted the buoy/channel marker to appear larger than it looked which is why I choose this focal length. If I have the opportunity to shoot them again, I will definitely opt for a wide angle shot.
