Last night a tornado struck Amity in Texas. We were the first rescue workers whom arrived in Amity. We got there about half a hour after the tornado hit the village. The sight was frightened. The biggest problem we had was getting into the village. Unfortunate, the road was blocked with cars and many damaged building, so we had to go in on foot. The injured were quickly taken to hospital one in another. However, another problem we had was the people who lost our homes. To our joy, when the news were posted on the Internet, and people from all walks of life helped the homeless.
