Well, this was sort of exciting! So Tom offered to lead us down to #5 since it was on his way home. From Traer we travelled south on US63 to PP Ave on our left, and headed south down that road until ended at 220th St. We turned west a short distance to P Ave and then headed south again. About 1/4 mile south of 245th we pulled up to the school.
As you can see, the south wall with the door is missing. There is a lean-too on each side, and the east side is for the cattle to come into some shelter.
UPDATE 10/14/15: We learned at a country school conference this past weekend that this school has been torn down.
