I have many memories of playing in the majors at Windsor Park and food is certainly one of them. We would get treats after games and if we did well, sometimes a parent would pay for "double treats".
A favorite for me was a blue raspberry snow cone. Popcorn would work but bubble gum was fun and choices includes Bubs Daddy or Fleer Sour Grapes, Sour Cherries or Rain-blo.
Bubs Daddy flavors I remember - Original (pink), Grape, Apple, Watermelon and Red Hot.
When there was a foul ball (or home run), kids would run for the ball knowing they could turn it in at the concession stand for a bag of popcorn.
