Trying to find the Old School House

In today's metal detecting adventure we look at a couple of sites that had early century school houses on them. Can we find any proof to support this? I know the schools were there that is fact. Has too much time gone by and too much fill been added. Where exactly the buildings were located is unknown to me. Lets try to use digging to help figure out this puzzle. Check out the video to see the outing.
