我在加利福尼亚州亨廷顿海滩摸黑出发跑步穿越美国，我是2011年洛杉矶到纽约竞走大赛为数不多的竞争者之一。

撒哈拉地区的岩画显示，人们曾利用马匹和马车来横穿沙漠；并且，在公元前300年至公元前200年间，有一些可以穿越撒哈拉地区的贸易路线。

Rock paintings in the Sahara indicate that horses and chariots were used to traverse the desert and that by 300-200 B.C., there were trade routes across the Sahara.

我曾乘坐冰川快车去瑞士旅行，大约8年前我坐火车穿越了中国。
