It'd been two years since the apes had last seen people.
It'd been 10 years since the events of previous film.
And? We had endless nitpicks about how the gasoline would have gone bad on TWD but people seem to be overlooking this huge plot hole in order to make the plot work.
Obviously that community lacks the resources to refine gasoline.
Oh no, believe me, it's a problem for me. Gasoline shouldn't have been useful to them and moreover considering the overgrowth of plant-life I doubt the power-grid would have been greatly intact. Nor do I even think the Golden Gate Bridge would have been standing after 10 years of no maintenance. There's a great number of problems with this post-apocalyptic premise.
Really? That's what you're going to get hung up on? It's so freaking minor. And you know, no one said anywhere that the GG bridge had no maintenance in 10 years, it's just been 10 years since the outbreak of the simian flu. For all we know, the GG bridge had maintenance up until 6 or 7 years before the events of the film. But hey, THAT'S NOT THE STORY OF THIS MOVIE! The movie is a speculative fiction about apes and mankind, not about whether the GG bridge would still be standing with no maintenance after a few years. If you can't enjoy the movie because of that, it's your problem, not the movie's.
