Estes Park, CO: We overnighted here on our way north. It's a really nice place with two specific things we wanted to see. First we did a drive through of the Rocky Mountain National Park. Beautiful place, but it was here that it first occurred to me that the reason I sometimes ran out of oxygen in the middle of speaking a sentence was because of the height of the mountains we were standing on. Just wow!
Second, being Stephen King fans, we had to stop at The Stanley Hotel and have a look around. Beautiful historic hotel with a claim to being the inspiration for the book, The Shining (although it's not the hotel in the movie). We didn't have time for the tour, but they do also claim to be haunted so I may go back some day and check it out!
