A Forsyth County man wants to give back to the charity that he says helped save his son’s life.

William Anastasio, a 25-year veteran of law enforcement, has invited the public to participate in “Tristan’s Ride,” sponsored by the Blue Knights Police Motorcycle Group.

Proceeds from the ride will go to Angel Flight, a nonprofit organization of pilots and volunteers who arrange free air transportation for charitable and medically-related needs.

Registration begins at 9:30 a.m. Sunday at Killer Creek Harley Davidson on Alpharetta Highway in Roswell.

The ride will make stops in Cherokee and Forsyth counties before ending at Ethyl’s Diner on Alpharetta Highway in Roswell. Cost is $25 per rider.

The ride is a dice run. Riders will toss five dice at each stop and get a score before continuing on to the next stop.

The rider with the highest score at the end wins $300. The second place award is $200 and third place is $100. Door prizes and T-shirts will also be given out.

Anastasio said the nonprofit organization’s help inspired him to develop the ride.

He said his infant son was diagnosed last year with chiari malformation/brain compression, a painful illness that causes the brain to push against the brain stem.

His son, who at the time was 5 months old, was not able to take a commercial flight for treatment at a facility in Cincinnati because of cabin pressure.

“The good people at Angel Flight flew us up there for the surgery at no expense,” Anastasio said. “They were lifesavers. My son’s surgery was nothing short of miraculous.”
