Several states later I was still thinking about the hitchhiker.

驶过几个州后，我仍着那个搭便车的行者。

In 2015, Canadian researchers sent a robot hitchhiking across the US. It didn't get very far.

2015年，加拿大研究人员派一个机器人美国搭便车行。 它没有走多远。

Any advice if I were to take a road trip again or if somebody else is thinking of hopping on a freight train or hitchhiking?

- 如果我再打算来一次路行，或者有人搭货车上路或搭便车行，有什么建议吗？

My brother, when he was 17 or so, he just decided to go hitchhiking and he hitchhiked down to Reno from Idaho where we were and ended up loving traveling but hated being dependent on other people.

- 我弟弟他十七岁左右的时候，决定去搭便车行，他从我们所的爱达荷州一路搭便车到里诺，最后他很喜欢行，但讨厌依赖别人。
