When I was little I thought my grandma owned the water tower because the only one I ever saw was on the way to her house so I associated it with her. Now I'm 27 and I still say "Look there's Grandma's Water Tower" when we go past.
I also used to think people worked up there purifying the water and went up and down the ladders but I never actually saw anyone doing it.
