"Whoever was camped here moved to higher ground when the fence went down," Naomi says, motioning to the top of the highest water slide. With the stairs barricaded, Alicia says there's only one way up: the side itself.
After quickly dispatching a pair of water-logged zombies, the two find time for a little levity, bonding over the sweet, sweet deliciousness of a deep friend cinnamon stick. "So what's your record of churros in a single visit?" asks Alicia. "4, I was having fun, may have been high on chlorine," responds Naomi.
