Pennsylvania College Senior Lives in Forest Hut Outside Campus

Before living in a self-made hut, he slept on hammocks in the woods and caves.

But even more improbable is that student Dylan Miller, 22, says he has already been living outdoors consistently for the past two years.

"I got sick of living in the dorms, and I thought I could save $4,000 a semester living outside, where I love to be," Miller told ABC News today. "I'd set up hammocks in the woods, and I took shelter inside caves during the colder months."

Last summer, his dad suggested he live in the woods for his senior project like American writers Henry David Thoreau and Ralph Waldo Emerson, whom he had read avidly, Miller said.
