What should take the place of the question mark?
The answer is
The rebuses refer to
The lyrics to "Can't Stop the Music" by the Village People
Take the cold from snow
Tell the trees, don't grow
Tell the wind, don't blow
Take the spark from love
Make the rain fall up
Take the heat from flame
Try not feeling pain (pane)
Change the master plan?? (this may be a stretch)
Music on a plane???
take the hope from man
You can't stop the MUSIC
And your not usual townfolk are
The Question Mark should have the word "Stop" (so it's a negated Stop Sign)
The symbols describe a small (2200+) town, they love fireworks, they talk a lot, they have no trees, they're farmers, it's hot in the summer and cold in the winter, it's not windy, they have windows & not air conditioning, new ideas leave, and they're in the East (and a bit North).
They don't have or need any Stop Signs, there's only one road.
