When our restaurant business failed, we headed north in a camping truck to Texas, hoping to have a “fresh start”.

At the     of Palo Duro Canyon (峡谷) State Park, I     a job advertisement hiring park hosts. The position offered a     , permanent campsite in the park, and     , the hosts served as a link between the park’s guests and the rangers (护林人). It was the perfect solution: a rent-free place to reorganize our lives. We entered the park and I made an     for the following day.

The park was     , so it took us some time to find an available site. That evening, as we finished our dinner, my wife saw two large skunks (臭鼬) walking toward our table. We     climbed onto the table and, for the next four hours, waited for them to     our camp.

Having survived that night, we were     that everything else would be all right. The next day we met with the people who ran the park. They explained our    and gave us a beautiful campsite.

That evening,     , we learned about the canyon     . They were strong and cold, rocking our little camping truck violently, and we lay     in the dark until the winds died away.

    the weeks that followed, we learned to survive in our truck and     the little money my wife     by substitute teaching. Building a successful business and then losing it had left very little time for building a successful     . For a time after our business     I thought I might lose my family as well.

Living in the tiny     with no television, we sat close together reading and talking. One evening, standing under a jeweled sky, I found myself     for all the hardships. We had walked the trails and climbed the canyon walls. We had become a family!
