Now they obviously still exist, but they were a staple of my childhood. Since I lived half of my childhood without the internet, boredom would strike often. So being outside was common and I remember hearing the music. But it was hard to tell where "The Ice Cream Man" was as he could be across the block or down in an apartment complex nearby. The best part was that you can't find most of things on the truck at the grocery's freezer section. I always liked the ice cream with characters that had gumballs for eyes. They also had one with Looney Toons characters where you could collect the plastic pieces as they'd all feature different characters. Bugs Bunny was the Holy Grail of them from what I remember, but nobody from my brothers to our friends got it from what I remember. I do remember using a whole allowance once and coming home with a big paper bag full of ice cream.
Did you ever visit the Ice Cream Man?
