if they're not idiots they can figure it out. I've been posting a lot about it on facebook. Furthermore, the point of the post is primarily a warning to protect my safety/let them know how bad it is if something happens to me, not necessarily to spread the word (which I've done plenty of). I don't want to encourage impetuous people to follow my actions unless they ask and think hard about what they are doing, because of the risk involved. Facebook is a "push" notification service, not a "pull" service.
