Hidden Door

A cold winter night
in pitch black darkness.
The harsh frost
leaves a nasty bite.
Most miss it
when walking by.
A mysterious door
to a building unknown.
Some may think
it's just another structure.
But very few know
of the truth it hides inside.
It's guarded heavily
by a chain link fence.
No one has ever discovered
the secret of the place.
And if anyone has
they do not matter anymore.
Those brave souls
are now in the grave.
