LOL. Did you actually think he was telling the truth? I’ve been following both those guys for years. They make great content. And the “real stories” that guy tells are running jokes of the channel that all the viewers know about, it’s true that he was American SF. But all he says are just jokes. You can clearly tell if you watch the video closely. He probably doesn’t even know about bonistan and thought it up on the spot, when this video came out even I searched up bonistan and tried to find some history. Even though I knew he was joking. Couldn’t really find much since it’s just a little town.
In short: nope, he was never here, just a running gag.
