Dot Saw a Ghost (childhood memory)

We would "go to town" to Roswell every Saturday night to go shopping and maybe see a movie, or to visit Mama and Grandaddy Boggs or Grandma Bagwell. One night when we were returning home, I saw a ghost!! We had to cross a railroad track as we turned off the Dexter/Roswell highway to get to our house. I looked down the railroad track and saw something white floating along the tracks. Everyone said it was just some paper blowing in the wind or some such, but I KNOW it was a ghost!!
