LOS ANGELES--- Two lost hikers who survived three nights in mountains thanks to supplies at a campsite of another hiker who disappeared last year described their suffering, saying they had “the real special thank” for the man who is probably dead. The couple, Allen, 24, and Brandon Day, 28, were in Southern California for an important conference. They got lost on Saturday west of Palm Springs after wandering off a trail during what was supposed to be a day hike. Prepared only for a brief hike, they wore light jackets and tennis shoes and had no food, spare clothing or mobile phone. With night closing in, they took shelter in a small cave and spent the night sleepless, freezing and hungry. On Monday, they discovered a campsite in a dead valley. There was a sleeping mat, a backpack, a disposable razor(一次性剃刀), a spoon and tennis shoes. Day and Allen were delighted, thinking someone there could help them find the way out. But later they realized the place was deserted. They found identification showing the camper was Donovan, 60, a retired social worker from Virginia. They learned later in his diary that he was an experienced hiker and he disappeared on May 2, 2005, in icy weather. They found articles in his backpack: a warm sweater for Allen, dry socks for Day and matches. They lit a small signal fire to attract a helicopter crew in the distance, but the crew did not see them. On Tuesday morning, Day created “a really big smoke signal” that finally attracted a helicopter crew. They were examined at a hospital and had only bruises(擦伤). “We feel great. We’re thankful. We feel like we’ve been given a second chance,” said Day, who expressed that they wouldn’t give up hiking even after this experience. 1. The passage most probably appears in ________.
