Authorities are trying to locate persons who may have been in contact with these people. None of the persons with measles were vaccinated. Why?

Food labeling is a tricky beast. For instance, when I read the words "cage-free" on an egg carton, I think it means that happy chickens frolic in a sunlit meadow all the livelong day until they're gently herded into a clean, sweet-smelling coop to lay a few dozen eggs—which I can purchase for a reasonable price, of course.

I don't know how many of you had this experience in your youth, but when I was a kid, I used to actively think about what would happen if I suddenly woke up in a fantasy land, or were to pass through a portal into another space and time.
