Um, you're the one speculating it is a "temporary" chain setup, are you not?
What makes your version "knowledge" and mine "speculation?"
I think, when considering the 2 versions, it makes much more sense that a proud owner would take a photo of a dog on a brand new chain spot ... than it does to ponder "why" anyone would put a huge padlock and swivel on a "temporary" chain spot.
Care to explain why the huge lock, and massive swivel, if it's only an "quick empty" setup![]()
