From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!
While Tally and David ride towards the city, David tells Tally a bunch about the world, especially about the Rusties.
For instance, David takes Tally through the empty wasteland created by the white orchids (romantic).
And they go through a Rusty city, where David explains that the Rusty civilization was destroyed because (1) they were dependent on oil (ahem) and (2) someone invented a disease to infect oil (which sure gives us some ideas for a fun weekend).
That's not the story that Tally learned in history class, but maybe the city doesn't want people to know that all civilizations are vulnerable. Hint, hint.
