While photographing Polar bears in the Arctic, with my wife and a couple of other photographers, we came across this large male. The bear came to our vehicle, stood up and put his head in the window. Our driver thought the bear was a little too aggressive and tried to start the van to scare off the bear. While doing so he nervously broke the key off in the ignition. We were all starting to get a little nervous as our driver radioed for help. We put a vise grip on the key, started the van and the bear dropped down. When help came, the bear became curious of the other vehicle and I took his picture from a safer distance.
