Troy Yocum is on a mission to make sure America's heroes are remembered.
The Iraq war veteran is walking across the country to raise money for veterans.
Troy Yocum has already walked more than 7,000 miles -- from Louisville, to Chicago, San Diego, New Orleans, and Boston. He visited Syracuse to honor a marine he's never met, to thank his family and to make a promise that every story he hears along his journey will be heard and remembered.
Drumhike.com reports that Yocum hopes to raise $5 million to help military families in need.
Yocum started his journey in April 2010, and, after the first 13 months, he had raised just $200,000, according to the Daily News.
Then, Mitchell Modell, the CEO of Modell's Sporting Goods, got friends to help Yocum generate another $260,000 in three months.
Now, after suffering through kidney stones, a foot infection and a neck injury along the way, Yocum remains determined to keep bringing hope to mourning families.
"They have fought for us, and now I will fight for them," Yocum told the Star Gazette. "If I reach the goal of $5 million, then many families will be helped."
