We had a wilderness survival camp last week. We went up to the Fielding family cabin and spent three days and two nights there. We built our own shelters and our lunch on Friday was find your own food. We also saw an animal track that some people thought was a cougar. It turns out that it was a dog. You can go to these websites for more information on animal tracks:
