Rail Road Crossing

The cross arms came down.
Then the commuter train sped past.
The motorist waited a short while.

Many humans crossed paths safely.
The plans of the clever engineers worked well again.

The patterns of the busy city continued like clock work.
Citizens interacted in the city like they have done for decades.

The essential machines and computers were fueled by electricity.

We glide through life unaware of what is happening around us.

Each intersection is a building block of our modern life style.
That rail road crossing is just one of critical parts of the whole.

Nature offers an abundance of beautiful examples of interactions.
Yet consider that the interactions in our cities are a little amazing.
