A Swan I Saw One Night

I came across the notes for this poem in one of my notebooks and I realized that I hadn't quite nailed it the first time.  There were still a few lines missing.  Here's the complete thought (for now).

A Swan I Saw One Night

A swan I saw tonight

Sleeping by the mouth

Of Weesuck Creek

Head tucked under

Its wing all but indistinct

A pile to the right and

Looking ass backwards

Much as I was

And outward

Towards the sea

Pensive and proudly

Surveying the night's

Indisputable truth

Not so much mindful

As empty and still
