At my request, Ronnie has worn his cowboy hat and boots (and nothing else, he's usually nude anyway) during a couple of our sessions. Mark probably wasn't thinking about the background of his photo.
Both of them have outstanding and spacious dedicated spaces in their apartment (Ronnie) or house (Mark), unlike some masseurs who have cramped spaces, place the table in the middle of their living area, or have homes that are really messy and not relaxing.
