My favorite was "John the Ice Cream Man" He was in his 70s/80s driving his what felt like a classic car filled with ice cream and pixie stix. It's sad to think he's probably passed since now, but I made sure to pay extra (which I'm also sure was my parent's money) to get ice cream from John. I remember me waving for him and he was just the sweetest man, a total grandpa vibe from him. One of my lesser dreams was to have an ice cream truck like he did. Now looking back, I don't remember too much, but I remember him so fondly.
