I had this thought. I think it’s because they’ve used mortar/cement when these are supposed to be drystone walls, and whatever the hell that concrete monstrosity is.
I'm thinking of changing the post title to make it more obvious. Don't want to feel like I'm taking credit for someone else's project. I just thought it was a nice wall!
I once replied to a comment about the first half of a one sentence post body. They didn't read the second half of the sentence. Comically they replied with it being due to lack of sleep. Love this community.
