SHEPHERDSVILLE, Ky. - A 24-year-old is making his way across the country on a bicycle.

Carson Caldwell left his hometown near Garnet Valley, Pennsylvania on June 29. He traveled more than 900 miles and made it to Bullitt County almost a month later, on July 22. 

"It's been challenging, but it's good exercise," Caldwell said.

Kentucky isn't his final stop. Caldwell hopes to cycle more than 3,000 miles and wrap up his journey at the end of Route 66 in Santa Monica, California. He's doing it to raise awareness for Yemen's Humanitarian Crisis.

"It's been raining, it seems, more than it normally does. It's also extremely hot and humid. These things are pretty minor when you consider the types of things that people are struggling with in Yemen and other countries," Caldwell said.

The Washington Post reports that some 8 million people are on the brink of famine and that millions of people need urgent help. When Caldwell learned about their plea, he says he felt helpless and wanted to do what he could.

"We've got a target goal of $50,000. Ideally, I'd like to exceed that."

Caldwell is raising money for Baitulmaal. The relief organization is based in Irving, Texas. Caldwell says that the cash will go towards food and cholera kits, to treat victims of the disease.
