Unless those rockets are capable of trans light speeds, they didn't go far. My guess is a highly radioactive spot on earth, the moon at most (radioactive moonbase maybe). Though I do like the idea of Followers who didn't make it back to REPCONN in time to leave on the rockets. A long pilgrimage to the rockets only to miss the ride. If I had to be a ghoul I'd like to be like Jason Bright; an intelligent glowing one. Never need a booklight again. :wink_smile:
