Cody Clements had planned to walk across the USA, interviewing people about happiness along the way.
Three days into his nine-month journey, Clements packed it in.
Clements graduated from St. Vincent College this year with a degree in theology and philosophy. He said he planned to think about his life journey while walking across the country.
He was carrying a 54-pound bag on his back. He had a tent, sleeping bag, and portable stove. His goal along the cross country trip, which was supposed to wrap up in May 2016, was to interview people, asking what made them happy. He planned to make a video documentary.
"I am buying food as I go or just making food. I am deciding my future and visiting family, some that I have never met, along the way," he said.
On Wednesday, Clements announced on his Facebook page that he was ending his journey. He cited his reasons as being "very little shoulder space and smoke blowing toward him" on the highway. He also said he nearly got hit by vehicles, lack of bathrooms, not knowing where he was sleeping at night were all challenges that drove his decision to end his trip.
