Why Costco?
>How does /x/ plan to survive this Paranormal experience?
Do the shelves auto-restock themselves? How do you deal with trash? Is there somewhere to put the dirt you dig out? I guess we'd need to start building labs with the equipment available, digging new labspaces out from under it - I think Costco has concrete to work with for new underground walls? What happens if we undermine the whole store? I assume it doesn't just float there, so we need to reinforce it as we go? I guess we research biological immortality and how to build portals to escape. Should be enough hardware there in various devices to make that relatively easy, and plenty of computing power if we DIY server farms from the consumer-tier computers that perpetually restock themselves.

You ever been in the back rooms of stores? Huge tracts of empty space. We'll be fine for a while. There are probably crawlspaces and whatnot, too.

We're not going to be digging out any underground cities, though, unless we find some natural caverns, or the trash chute in the back functions as a magical disposal, like how the sinks magically generate water and the vents magically generate air.
