美国有哪些值得旅游的城市呢？

今天想跟大家介绍一下我winter去的Denver这个城市，顺便也介绍介绍我的City Houston，还有一些其他的大城市。

The characteristics of Boulder, Denver Colorado: dry and cold; lots of mountains and hills, a huge snow mountain behind my friend's University and it's beautiful and cold! Not that diverse like Houston.

Houston: very diverse which is considered as a melting pot of America. It blends lots of adjacent cities into it to make it larger and more diversified. That's why we have a large number of food branches. 

NYC: New York City, the big apple. Many famous attractions: Status of Liberty, Empire State, Metropolitan Museum of Art, Central Park, etc. 

California: San Francisco & Los Angelas (generate the majority of wealth and tourists). It's the coastal state to make it own one of the most perfect and wonderful weather. 

In the following shows, I want to discover more American cities with my local friends about their special geography and characteristics.
