This was from an IG story at Park of the First President about 7 hours ago. It's hard to tell, but in the very back it looks like there's a big white lighting kit either for a pit stop or for another interview. You can see two people standing there like they're being interviewed.
Really hard to see though, especially because I had to lower the pic's quality in order to post to RFF.
I wonder if this "wedding" had anything to do with the show.
