I saw an interesting post here about comparing RMNP to Yellowstone. Much to my surprise, the overwhelming majority of posters said if they had to do one park they would do Yellowstone. It got me thinking, because although I've never seen Yellowstone it always seemed not that scenic in pictures and just about the geysers. I know this is probably ignorance, but it was my impression. So, can anyone be clear about what the tremendous pull is for Yellowstone, why is it a must see in your lifetime kind of park?
Also, comparing Glacier to Yellowstone, if I had to pick one for our next trip, which is best? Or is it possible to do both in the same trip, perhaps 2 - 3 days in each place with a travel day in between? Or is that not enough time to see things?
(I think I'm in travel withdrawl after our incredible trip to RMNP so I'm already thinking of next year!)
