此次旅行主要交通工具選擇了巴士，包括灰狗巴士跟megabus。而且我發現提前半個月或一個月前訂票，價格會便宜很多。像我買灰狗是半個月以前，就買到大約半價，另外也有聽說可以買到1元的megabus。
This Trip I choose buses as my major trasportation, including greyhound and megabus. I found if you book before 14 days or 1 month, you would have discount. For example, I bought greyhound ticket 14 days ago, the price was $45 instead of $90. Some people said you can buy $ 1 at megabus if you are lucky.
The price is:價格如下
