I'd like the option to return to a random visiting stone, as I think if it were forced it could discourage those who want to visit home streets only from visiting the home streets. (Yep, I know exploration and "getting out in the world" etc is good! But I think there'll always be the people who would want to return to the same visiting stone, and I'd not like to see home streets not benefit from the visits that some of them wouldn't be taking, if they had to be returned to a different place.)
So how does one go about getting on the Visiting Stone list? I have a whopping 4 cultivatable items on my street, yet my rock has nothing to say on the subject.
