The porch appeared to have been added on after the school was built. Looking inside the porch, you can see that the original front door was recessed, as we have seen on other old schools.
The school is now used to store hay bales. This shot is looking from the front door, while the following two shots are taken from the hay pile looking back towards the door.
It appears as if someone hit the corner of the building with some farm equipment or something.
3/4/13: Thanks to Roger Young for identifying this school.
