Ghost Rider at Kennesaw Mtn.?

[A] man, who doesn't want to be identified, says he and his teenage son were driving through Kennesaw Mountain National Battlefield the night of October 8 when they spotted something about to cross the road in front of their car. Both Civil War buffs, they say the rider appeared to be a Union Army cavalry officer complete with a sabre in his hand. "I quickly locked down on my brakes as the horse proceeded to come right in front of us", the driver says. He says the rider then headed straight through a fence as though it didn't exist and faded into thin air. "My son and I were in a state of almost sheer panic," the man says, "but we managed to maintain and get on the way home very quickly."
