ATLANTA -- A courageous 3-year-old boy who has no limbs will be getting help from some special "hogs" next weekend.

Memphis Lafferty lost his arms and legs to bacterial meningitis when he was six months old.

The only way to survive the potentially deadly infection, doctors said, was to amputate his limbs.

Memphis has learned to get around on prosthetic legs.

“He's a trooper. He doesn't realize what's happened to him,” said his father, Christopher.

But Memphis’ parents know all too well that the cost of their child’s care is enormous. Memphis’ prosthetic legs cost up to $70,000 a year.

So some motorcycle enthusiasts will gather Saturday at a Harley Davidson dealership in Marietta for the third annual Poker Run, which will raise money for the boy’s treatment.

“It’s just grown every year. Every time I look at Memphis, it does my heart wonders knowing what I'm doing to help him and his family,” said event organizer Jay Ballard.

“It just shows the heart and compassion that the city of Atlanta has for my son, because it takes a city to raise a child like Memphis. It’s amazing what's happened,” said Christopher Lafferty.

“We appreciate everything that everybody does. He's a tough little boy. He's overcome so much and he continues to with everything he does,” said his mother, Leslie Lafferty.

Registration for the Poker Run begins at noon on Saturday at Earl Small's Harley Davidson in Marietta.
