Thanks to all who replied. The only reason I questioned this requirement is, of the few people who have visited I don’t recall that they commented on it. I am a “ rules” person so if we go I will do as instructed. And, yes, I agree it really is not enforceable. Kind of like here in Maine. People from NY are suppose to quarantine for 14 days. An impossible mandate to enforce. Such is the world we live in.
