Al Zolynas: Under Ideal Conditions

say in the flattest part of North Dakota
on a starless moonless night
no breath of wind

a man could light a candle
then walk away
every now and then
he could turn and see
the candle burning

seventeen miles later
provided conditions remained ideal
he could still see the flame

somewhere between the seventeenth and eighteenth mile
he would lose the light

if he were walking backwards
he would know the exact moment
when he lost the flame

he could step forward and find it again
back and forth
dark to light light to dark

what's the place where the light disappears?
where the light reappears?
don't tell me about photons
and eyeballs
reflection and refraction
don't tell me about one hundred and eighty-six thousand
miles per second and the theory of relativity

all I know is that place
where the light appears and disappears
that's the place where we live
