famous canal in Hawaii

This is ala wai canal that is near our domitory. This is fomous in Hawaii. However, if you see this, you will think this canal is so dirty. Yes. Although, most sea is very beautiful, for example, waikiki, the ala wai canal looks so dirty. The water color is green or sometimes blown... We should clean someday.

By the way, there are many people paddle on the board in ala wai canal. It has become the famous sports in Hawaii. Sometimes, people who is in the board dropped to the canal from the board. Although, I saw this several time, everyone became dirty.
