Slap of the screen door, flat knock
of my grandmother's boxy black shoes
on the wooden stoop, the hush and sweep 
of her knob-kneed, cotton-aproned stride 
out to the edge and then, toed in
with a furious twist and heave, 
a bridge that leaps from her hot red hands
and hangs there shining for fifty years
over the mystified chickens, 
over the swaying nettles, the ragweed,
the clay slope down to the creek, 
over the redwing blackbirds in the tops
of the willows, a glorious rainbow
with an empty dishpan swinging at one end.
