We did not have ice cream trucks either. (Too far out I'm the country) I always envied the kids on t.v. who chased the musical trucks. Now I know being raised in the countryside is better than having an ice cream truck. Lol.We didn't have ice cream trucks, or if we did, my mom never bought anything off it. I didn't know they existed outside of TV until I was in college.
I do remember orange sherbet in those rolls... it was called a Push Up. And they only came in that one flavor.
I'm pretty sure they only had the orange push-ups when I was young.
