Carival show is mile marker of Americana

It's officially summer.  I followed home a few semi-trailers pulling "transformer-like" pieces of carnival rides and waffle cone stands on their way to be assembled into a county fair.  Obviously aging, these pieces of rusting mechanical metal bring back floods of memories small town carnival experiences as a child.  (Later when older, it was all about the beer tent.)  Who are these roving bands of people?  I picture a truck stocked with large pipe-and-socket wrenches at the ready to tighten rusty bolts... miles of long black electrical cords with plug-in jacks the size of a cereal bowl.  Zig!... Zap!...and suddenly neon electrifies the darkened sky and the air is filled with energy and glow.  Amazing with the competition for entertainment that this basic level of fun still exists today.  Where will they end up down the road?  And will they haunt us with carnival tunes emanating from the merry-go-round?
