One day in March，seven years ago，during happy hour at a bar in my hometown of Fayetteville，Arkansas，I made a surprise announcement to my friends：I was going to shut down my law practice and attempt to travel around the globe in a year.What's more，I would do it without taking any flights or making a single advance reservation of any kind.My announcement drew mixed reactions from my friends.Some offered support and encouragement，while others were more doubtful.
   Once I had said the words there was no turning back.It took months to shut down my practice and get things in order.Once I set off on my adventure in December 2008，I found travelling without using planes was not easy.Trying to circle the globe in 16 months （it took me a bit longer than the initial 12 months I planned） made it even harder.Even so，travelling overland was the most amazing way to truly understand the immensity （浩瀚無際） of our wonderful planet.
   I took three consecutive （連續(xù)） overnight buses to travel 3，000 km through Argentina，from Ushuaia to the capital Buenos Aires.I would look out the windows for hours on end of the completely unspoiled plains，as if humans had never touched it.
   It took seven consecutive days and nights on trains to get from Moscow to Beijing，each day spent staring out the windows for hours as the Siberian plains swept by.Sometimes，I wouldn't see a village or a human being for 10 hours.Later in my journey it took 22 days on a cargo freighter （貨船） to get from New Zealand through the Panama Canal and back to Philadelphia，to finish my round-the-world adventure.
   It turned out that travelling with no reservations was far less difficult than had imagined.Pulling into a city on a bus with a backpack，looking in a guidebook for a few suggestions of accommodations（住宿），and then finding an empty room was never much of a problem anywhere it also kept me flexible and open about all my travel plans，which is advice I give everyone who asks---plan far less than you think you should.
