Been chewing on this one for a week. Tell me if it feels underbaked.
The bar at noon is a long brown river. No one looks up when the door opens — the light is the door, the door is the light.
Should that last couplet be one line or two? It scans either way.
Engaging!
The first stanza evokes for me, first, a quick thought of The Crossing of the Bar, by Alfred Lord Tennyson. Then more immediately, the Missouri River as it runs through the Bismarck-Mandan area. My wife and her family grew up on the sandbars in the river. The Missouri was considered a wild river by the steamboat pilots, and the sandbars appeared and disappeared at a rate unheard of on the Mississippi. The sparse, direct, and specific language provides open air which invites such thoughts.
There is a decent argument that the four lines of S.2 should be refashioned into two stanzas of two lines each. There seems to be a natural pause where a stanza break will add drama to the M-dash positioning, and an increased subtle emphasis to the closing couplet.
That leaves the matter of the title. Here, the title will need to anchor the canvas to make this poem. My first impulse is to suggest "Kismet". Remember Sparky's admonition: If you don't have a worthy title then you have not committed to the poem.
So, in sum:
Kismet
The bar at noon is a long brown river. No one looks up when the door opens —
the light is the door, the door is the light.
You will note that the line breaks did not come through in my post. Here is what I intended to end my comment above with: Kismet The bar at noon is a long brown river. No one looks up when the door opens — the light is the door, the door is the light. I was able to do this with the right line ending by "quoting" your post and then editing it.
Here I try the cut and paste method:
Kismet The bar at noon is a long brown river. No one looks up when the door opens — the light is the door, the door is the light.
You see that the line endings didn't work by cut and paste.
The only other comment I have on this is that while I was writing my comment, I would have liked to be able to scroll up to glance back at your poem again, and that wasn't an option.
