I absolutely LOVE Yellowstone National Park. My fiance took me here in 2014 and it is one of the most amazing places. It is such a vast place which spreads into Montana, Wyoming and Idaho which gives you an idea just how vast it is. I am fascinated with Buffalo/Bison and was lucky enough to see a LOT of them on the day we went. No only did I see Buffalo but I saw bears & little chipmunks. Amazing scenery, geysers. Simply breathtaking!
