Changeable weather indeed! Somehow I dreamed of this sort of vista when visiting Yellowstone and here it was - wow what a holiday what a location. The fall had it all for me the scenery the wild life the sunshine the rain and the snow - never a dull moment.
And if that wasn't enough I found out you brew beer over there too, I thought it would be all Coors and Buds and Millers but not so - you have real beer and I liked it!
