It would be neat if it were true. Unfortunately, I have word directly from a trucker on the ground that there are plenty of trucks delivering to the city, unloading food and goods. The guy who started the idea talked to maybe 10 other drivers who agreed to take part.
"If you’re not familiar with what the title of this post is referencing, back in the 80s Mel Gibson made a third Mad Max movie, often referred to by one word as part of it’s title, “Thunderdome.” While the Thunderdome part and Tina Turner’s performance as the leader of a semi lawless trading post called Bartertown gave the movie character, overall the film fell flat when it’s writers forgot that the story needed an ending. One other memorable piece of the film was a character called “Master Blaster”, the foreman who oversaw Bartertown’s energy production, via methane from pig Schiff. Being a prickly character, Master Blaster would occasionally embargo the energy to Bartertown as a reminder of the power he held."Hell the "Planet Erf" middle with the dumbass feral children was the problem, not the ending.
All Mad Max's have the exact same ending: carmageddon.
