The town along Highway 66 is quite small, and no other tourists have been seen all the way. It's like entering a dream theater, only the two of us are acting, the rest are theater furnishings, really that is the rush. After buying the postcard, the navigation found the post office to buy stamps and send cards. The post office of the United Emperor is very easy to find, generally a stable building. On Highway 66, pick a postcard with the characteristics of Highway 66 and send it to future self and friends. The post office can buy a stamp and paste it, which is the most anticipated part of every trip.
