A couple years ago in New Hampshire at a place called the basin I was shooting from the edge of a river and the current was very strong due to a few days of constant rain. The river bed at this place is almost completely granite. So I have my 5d mkii on a tripod and its already in the water resting on the slippery uneven granite, I had to hold on just to keep it from being swept away in the strong current. So... somehow I decided it was a good idea to stand in the water right at the edge, I'm wearing boots and jeans, and have importaint things like wallet, keys, and cell phone in my pockets. So I lose my footing on the slippery granite and off I go down the stream with the camera in hand, heart beating a million miles a minute. Somehow I kept just the camera above water lever and managed to get my foot lodged into a ridge on the river bed, stopping me. The process of getting out of there was hell, the slightest wrong movements would send me sliding again, but slowly I got the hell out of there with everything intact.
