No particular reason. These are a childhood memory; we used to spend much of our summers at the Wisehaven Swim Club in York, PA. Mom would take us during the day. Dad would take us on weekends and after work. Life was simpler then.
Two candy memories from that era, as purchased from old pull-type vending machines:
Goetze's Caramel Creams, and Zero Candy Bars
For some reason, Caramel Creams pop up in the vending machine at work now and then, and on long afternoons like today I occasionally indulge.
