Amazing what I discovered. Borders are generally determined by landscape features and political/economic environments - not surveys! Everything is pretty loose. One country puts up a fence and the other side says okay or they have to negotiate. It's not written in stone. Wow! Thinking how the earth changes by erosion and earthquake, flood etc. it looks like the border areas can become pretty fluid over time. Apparently nobody is concerned about it. Unless it's the people at Standing Rock.
We had eight inches of snow yesterday, wind and temperatures from 23 - 35. Glad I had my yard/garage sale Saturday! But I know that the melting snow will moved some of my landscape (pecan shells) down the berm onto the sidewalk, temporarily at least changing the "border" of my yard. Is that called soil creep? And trying to stay on course with the intent of this chat line - the cold weather really affects my bladder!
