One of my favorite activities during my preteen years was going to Skateland North with my brother John. After he DJ'd at the skating rink we would go to Church's or Popeye's (along with hundreds of other hungry skaters) to eat and we always ordered strawberry soda to go with our meal.
I found strawberry juice in the supermarket today. Along with that I purchased some carbonated water. Add ice, mix the two liquids to your desired level of sweetness and you have Strawberry soda!
