My guess at the first pic is either A. a raccoon that is too close to the camera (thats what caused the all white and might be why it seems so big) and B. a coyote. just because of the furiness.
I guessed those just because your in kansas and I dont know what other fury animal like that roams kansas.

I also agree with PJ. That does seem like a great spot and with not having much traffic makes it seem like something is scaring them away.

Have you talked to the owner at all?
