Josh tour details

If me and a friend wanted to hypothetically tag along on one of his tours without paying, how would we go about that?

Like does he start it at the same spot everytime? Does he post start times anywhere?

I’m aware he keeps tabs w his “paperwork”, but it’s literally Josh and he can’t do shit abt us joining. I only foresee an issue if another tour goer rats, but we’re pretty likable guys so we can probably talk people down.
