Abandoned car
I guess abandoned cars, somewhere in the middle of prairie or park, is something normal around here. For those looking- I know for sure about two in Iowa- one is in Squire Point park on Coralville Lake (N 41 43.765 W 091 33.025), the other on the beginning of the Palisades Park bike trail in Decorah.
The rusty cars make up for great photos. Even more so, if the rust distinguishes them from the green environment. OK, this one needed a bit of encouragement to do that :).
To admit the credit where the credit is due, this photo was inspired by Darwin Wiggett, and his photo of rusty car somewhere in Saskatchewan.
