Okay, now that I've read this and am actually awake.

Not too sure about "expensive equipment" that can be gathered, given they haven't many resources themselves. Kate's idea is to at least have underground shelters if something goes down in the city rather than everyone running around not sure where to hide. Unless you mean what they already have on the ground, but it would be best to check in with specific groups (clinic, DITR) and see what they've got and are using.
