I think it has been determined that there are 2 pools. 1 is at the Biltmore, the other is implied to be in Rome.
Posting a question (from ignorance), Does the Vatican have a pool enclosed from the general ‘audience’?
I believe the question regarding Rome was more a point of fact the Podesta the molesta was there with Hillary the devil to meet with the current fraud pope. I don’t believe there was any hint of a pool there.
