After Sierra leaves, you head down to the market, grab some borax for Lether, and look for June to get the rest of his order. Balls tells you that "Vinegar" packed up shop and bought passage to Depot. He mentions that she just missed the blockade, then jokes that you didn't.
With your work done here, I'm guessing you want to get back out on the road, right? Sure enough, there are still three trucks with a big fuggin' turret sitting at the end of the road. A few football fields of road to build up speed, but that's also open ground for them to take aim, which isn't good. A few bikes out there, too. Trouble with a capital T.
You could just... pay the toll and head through.
What do you do?
