 excerpt: "I started taking photos when I was 15 years old, in photography class at Noblesville High School. With our hand-made pin-hole cameras in tow, my friends and I would search for abandoned trains & run-down houses in rural Indiana. I loved getting lost in the woods and then finding something that had been lost to the world."
