I'm a strong proponent of the personification of buildings and man-made structures, a theme I'll return to in a drawing later this week. If the dreams of the first two water towers are reminiscent of scenes from the movie Super 8, it's likely because director J.J. Abrams read this comic when it first appeared in the newspaper or on the blog last year. So yeah, just a coincidence.
Finally: if you ever decide to make an Incidental Comics-inspired pilgrimage, you can actually visit the last two water towers. They sit just a few miles down the road from each other in Derby and Mulvane, Kansas. Though I'm pretty sure the cornfield is now a big box store or strip mall.
