Sometimes, we observe things that we just can’t explain.
This crop of blue posts was actually pretty far away, my feet were getting cold, and the nearest parking area had those sawhorse blocking things with a “Closed” sign. Thank goodness for my telephoto lens.
If I had to guess, they look like those protective coverings that can be placed around trees to keep deer from demolishing them, but I don’t see the trees.
Any other guesses?
