Aidan Hornaday may only be 12, but he's got his sights set on big things. The Woodstock boy is trying to rally kids all over the country to make a difference. The youngster has created Aidan Cares. He wants to prove to kids and grownups that everybody has something they can use to help other people. He found his something when he picked up his big brother's harmonica four years ago. The next night, waiting for his mom at C & S Seafood Oyster Bar in Vinings, Aidan took off his cap and started playing. "[I] was blowing harmonica, one note, then looking at it, then blowing another. And then, out of nowhere, I got $80. And I thought, 'Wow, 80 bucks for taking my hat off,'" said Hornaday. A 7-year-old philanthropist was born. "That night I came home and I said, 'You know what, I'm going to donate this $80 to African orphans to help fight intestinal parasites,'" said Hornaday. Soon people were asking him to play at their events and inviting him to speak to them. And the more he played, the more donations rolled in. In four years, he's raised more than $60,000.
