I was watching News Ch. 4 at noon and they had this 10 year old kid that had collected hundreds of vacuums. His idea of dream vacation was going to different vacuum museums across the country. I couldn't find a video, but found a similar kid on YouTube, this isn't the same kid, but you get the idea.

Interesting. One of my autistic guardian ad litem kids had a thing for vacuum cleaners, too. He had a collection and showed them to me every chance he had. He used to carry pictures of them with him when he wasn't at home.
