One thing I dislike in America.(Hill)

  One thing I dislike in America is transportation fee. I have been America for 3 weeks and I have gone to SF for many times. I find that the bart and the bus fee is expensive, for example, if I take bart to union square, I should pay almost 4 dollars and if I take bus in SF, the cheapest bus take 2 dollars. So, I think it is very expensive compared to my city. In my city, the longest metro route fee is just less than 1 dollar and if I have bus card, the bus fee is only less than 1 dime. Because our city government donates a lot of money to the transportation, I can enjoy such a cheap price. So, the transportation fee in America is very expensive for me.
