Many of the flagship wildlife documentaries have confirmed my love for certain places but at times they have shaped my photographic aspirations in terms of places I want to visit.  The 2009 BBC documentary series on Yellowstone was most definitely one of the latter and especially the winter episode and my first visit in 2010 confirmed it was a good decision. It is certainly busier now than then but winter is the quietest of all the seasons her and in terms of wildlife photography the most dramatic, unpredictable (which is good in my book) and quietest time to be there too.
