Study for magic suit (name undecided)

to build the neighborhood
where his house would sit
a giant hole
for all the rain to gather
the crane's that dug it
so deep and tall
could not be gathered or salvaged
abandoned in that great hole
they hit a giant spring
and hole filled right up
with crystal clear water
crane in a watery grave
from our dock it could be seen quite clear
30 feet below the surface
once old enough to swim
would swim down toward the great beast
just to touch the tip was the dare
then we became older and more bold
and stronger and we swam deeper
a deeper plunge to touch the cabin
where the worker once sat
and deeper still
to momentarily peer through the window
noticed something left behind
appeared to be a briefcase
left behind by the crew
had to abandon the crane quite quick
training every day
improve breath holding
efforts to oepn the cab door
final effort to grab the case
almost passing out
bringing the case to the surface
open on the dock.
