There is a region of Kansas referred to as the "Flint Hills." Some of the locals have explained that when settlers from the east first arrived and sought to clear fields for planting, they pulled countless rocks and boulders from the ground - many left from the glaciers of the last ice age. Those rocks were used to build homes, barns, and fences - many of which are still standing today.
Not sure what this was, but was certainly startling to come upon. Looks like a Knight, or maybe Don Quixote, made from lots of scrap metal welded together. A unique mailbox post!
