A few years ago I was asked to speak at a conference at Mt. Washington in New Hampshire. I went in a day early, so I had time to ride the cog-railway to the top of the mountain, went out of my way to book a coal fired steam train. It was spectacular. When we got to the top the mountain was in a heavy fog. I loved it.
I read recently that there is a proposal to build guest accommodations, a hotel of some type in the national park at the top. I might need to go back.
