that’s
true,
but.
..
...
half
the time
we’ve been down
for
repairs
.
you’ve been here
more than
two
weeks
and hardly
gotten anything
done!
I think I see
the
real
villain
in this situation.
what do
you mean,
bonnie?
what’s
causing
this
-?
during the
day, the ground
thaws
when
the snow and
ice melt.
“...and the more
firmly fixed
in the
mud it becomes.”
“the deeper the
mud, the deeper
the tracks sink.
..”
a vehicle left
sitting in mud
will freeze
in
it’s tracks
overnight!
then, when the
sun goes down,
the mud
freezes
as hard as
concrete
.
“the mud gets
soft
and wet.
..
and the tracks
sink in
.”
and that
takes
time
.
when that happens,
we gotta take the
broken track off
and replace it.
