In the corner of our yard was a locust fence post that was placed as a boundary corner to my grandparent's farm. It lasted for several decades and was still standing the last year before we sold the home. The posts are durable, rot-resistant and so strong that they are often the first choice for roof-support posts in the coal mine.
I will always have a special affection for the locust and how sweet their flowers are.
We were such lucky kids.
