I don't think this is garbage truck specific fascination. Many years ago, I recall reading a story about a father who noticed his kids being glued to the apartment window watching a construction site next door. They were fascinated by the large and loud machines. He built a DVD video business from filming busy construction sites for kids. It was a success. Kids love big loud colorful things that move.
