I opened the rat-proof metal box where I kept my food cache and took out some bottled water and a packet of powdered milk. I mixed these together in a bowl, then dumped in a generous serving of Fruit Rocks cereal. Once I’d wolfed it down, I retrieved an old plastic Star Trek lunch box I kept hidden under the van’s crushed dashboard. Inside were my school-issued OASIS console, haptic gloves, and visor. These items were, by far, the most valuable things I owned. Far too valuable to carry around with me.
