America’s love of cars and being on the open road has led to the creation of the modern travel or camping trailer (露营旅行车). Some trailers are so well equipped that people can comfortably live in them full time.

Almost all campers (露营车) are considered as recreational vehicles (RV’s). RV’s include motor homes, trailers, house trailers and truck campers. The smaller trailers usually have just enough room for two people to sleep and store a few personal travel items. Some of the larger motor homes include a kitchen, a bathroom, an eating area and even a bedroom.

While tent camping is always an adventure, campers are a fun way to take a long trip, or to spend some more comfortable time in a beautiful setting, like a lakeside campground. So many camper trailers have been designed for people to live in the trailer long term. Some people choose to park their trailers in trailer parks and live in their trailers full time. In America many retired adults choose to spend their time traveling across the country on the open road and bring their trailers with them. Full time use of trailers for these travelers is considered to be a recreational (休闲的) activity.

Camper trailers can also be rented and used for a shorter period of time, such as a camping trip or a road trip. A camper trailer can be a comfortable alternativeto sleeping in a tent if you are camping. If you like traveling at your own pace, a camper trailer is a good choice.

Walking down a path through some woods in Georgia, I saw a small pool of water ahead on the path．I angled my direction to go around it on the part of the path that wasn't covered by water or mud．As I reached the pool, I was suddenly attacked! Yet I did nothing for the attack．It was so unpredictable and from somewhere totally unexpected．I was surprised as well as unhurt though I had been struck four or five times．I backed up a foot and my attacker stopped attacking me．Had I been hurt I wouldn't have found it amusing．And I was laughing．After all, I was being attacked by a butterfly!

Having stopped, laughing, I took a step forward．My attacker rushed me again．He charged towards me at full speed, attempting to hurt me but in vain．For a second time, I took a step backwards while my attacker paused．I wasn't sure what to do．After all, it's just not everyday that one is attacked by a butterfly．I stepped back to look the situation over．My attacker moved back to land on the ground．That's when I discovered why my attacker was charging me only moments earlier．He had a mate and she was dying．

Sitting close beside her, he opened and closed his wings as if to fan her．I could only admire the love and courage of that butterfly in his concern for his mate．He had taken it up on himself to attack me for his mate's sake （缘故）, even though she was clearly dying and I was so large．He did so just to give her those extra few precious moments of life, should I have been careless enough to step on her．His courage in attacking something thousands of times larger and heavier than himself just for his mate's safety seemed admirable．I couldn't do anything other than reward him by walking on the more difficult side of the pool．He had truly earned those moments to be with her, undisturbed．    

Since then, I've always tried to remember the courage of that butterfly whenever I see huge barriers facing me.
