I usually do not take part in photography contests but, this year, I submitted one image to the 2010 Best Holiday Picture Contest organised by the company where I work. And I had the nice surprise to get the third prize in the contest with the following picture. You may already have seen it on my Wyoming & Utah photo trip page. It was taken early on a cold September morning, on the car park of the Grand Prismatic spring in Yellowstone National Park (Wyoming). I still wonder if this sign was meant as a joke or if it was real ! The huge smoke cloud at the back is caused by vapour coming out of the springs in the cold autumn morning.
