Austin, of Alpharetta, was born with an intestinal disorder and a heart abnormality and has made a complete recovery.

He and Wills also drew awareness to the Children's Miracle Network campaign running through May 31 at Wal-Mart stores and Sam's Clubs. Buyers purchase $1 paper balloons in the fundraiser.

The Children's Miracle Network brought its 70-foot tall hot air balloon, but it had to take it down because of high winds.

Wal-Mart and Sam's Clubs in Atlanta have raised more than $455,000 for Children's Miracle Network through sales of $1 paper balloons and special store-wide activities by associates. Last year, the $1.4 million raised by stores and clubs in Atlanta helped enrich the lives of more than 233,000 children, of which nearly 65,000 were from Cobb county.
