2:食物费

　　A:在美国食品价格约是中国的7倍.鸡肉牛奶很便宜,蔬菜贵一点点.但所有的美国超市都有折扣的商品.你可以有一个VIP卡打折后很便宜.

　　B:麦当劳.肯德基是很便宜,约是中国的2倍.墨西哥的TACO也很便宜.除了麦当劳.肯德基其实还有很多别的东西,例如JACK IN THE BOX......

　　C:或你可以询问过期食品,大部分超市会给你.刚刚过期的食品不影响质量.

　　因此我在美国，每天大约10美元(约70元)的费用,很便宜.

　　如何获得美国签证

　　http://www2.biketo.com/bbs/thread-93345-1-1.html

　　10月20日 北京-旧金山

　　一个晚上没睡整理行李，其实是打算10月21号走的，因为那是我美国签证的最后一天也正好是凯路亚克离开我们40年的日子，不过我总觉得美国移民局不会让我入境，所以选择了提前一天。但说实话心里还是有些担心，因为不知道中国海关会不会放行还有就是美国移民局会不会让我入境，不过无所谓，就算失败了也算做过了。

　　10点多北京机场起飞，在香港转机，然后飞行了估计16个小时，于旧金山当地时间10月20号中午落地，感觉时间停滞了，其实只是时差。出关很顺利，移民局的人根本没有问我想象中那么多的问题，而他居然也给了我6个月的停留期，这个确实有点是意料之外的事情。一般来讲第一次入境美国只给一个月的停留期，最多3个月，所以我的往返几票定的是3各月的，但是他给了我6各月，太牛比拉~~看来我是值得信赖的人。

　　旧金山的落脚地是大学同学宜宜家，我一直以为她是中华民国的护照，但原来她是中华人民共和国的公民……

　　All night I did not sleep, because I was packing and waiting for the sunrise.

　　7:00 am I left home, standing alone on a Beijing street corner in the early morning I felt a little bit sad and lonely, then I took the subway to the airport.

　　10:00 am the airplane took off from Beijing stopped for a couple of hours in Hong Kong, and landed in San Francisco at almost the same local time that I left from Beijing, but I flew more than 16 hours already.

　　My American visa's expiration date is 21 Oct, which is very fateful for me, because my idol Jack Kerouac, died on 21 Oct 1969: It means that I stood on American soil, 40 years and a day after he passed away. I did not choose the exact day-21 Oct- because I do not want to get any trouble at the customs in San Francisco.

　　I prepared a lot of answers for the American immigration, but they did not ask me many questions and gave me a 6-month I-94 card! I am very surprised: usually, the first time come to America just get 1-3 months, I am so lucky.

　　I stayed at my university classmate's apartment in Berlingame, south of San Francisco. This time I did not bring my bike from Beijing, it is too difficult when you get on and off the plane, so the first thing I needed to do is buy a bike. I am pretty lucky I got a used bike for $ 150, it is a Specailzed - almost new one, and I bought two used panniers, a front rack and a front bike light, etc for $ 110.
