(by David Citino)
Steerage: The part of a passenger ship reserved for those traveling at the cheapest rate.
A photograph can show us,
in color or in black and white,
what's wrong, what's right.
Look with me inside this ship.
We see, through the lens, a crowd
of families. It all looks loud,
though a photograph makes
noise only in our heads. Lives
are changing. Husbands, wives
and babies are sailing toward us,
who inhabit the future they desire,
free from poverty's dirty fire.
They sail in steerage, a mode
of going from dark to days
of light, to develop all the ways
of being themselves. The mast,
they hope, will grow into a leafy tree
and whisper, "Now you're free."
