So, here is what I gathered.
GFCI is a different type of protection than a normal circuit breaker.
If I can find the outlet that is first in line, I can wire one in there and then the whole run beyond is protected.
Now, one last question... White or Black, which goes where?
KULUTZ posted a correct example of in-line wiring from a GFCI recep. and to put it into words; with the face of the recep. facing you and the ground stake down, the hot, (black in your case), goes on the right, the neutral is on the left.
