Among the national parks I have seen so far, the Yellowstone is certainly one of most impressing one.
Nowhere else can prospering life and death be seen so closely side by side. In a sense, there is even
beauty in death, such as dead white trees ...

Some people think, Yellowstone is overcrowded by millions of tourists. Don't worry: Just a few minutes
walk along one of these nice trails, and you're pretty much alone in wilderness. There is still one thing
I wish to see: Yellowstone during winter time. The contrast of hot steam and ice and snow must be overwhelming.
