You go to the library where its maybe harder to trace your internet activitys. You exchange your library card for a key to one of theyre computers. You find out this sort of creepy event involving an ambulance is something of a urban legend. You find a link to a forum speaking of it. You sign on as Todd Mathers and chat with people there. You find out much about the ambulance's patterns and weaknesses. You feel much more prepared to deal with it if you see it again. And according to the people in the chat room, you WILL see it again.
