I go to my assigned grid and stay there. If after a week I've seen no traffic at all then I roll a six-sided die. If it comes up 1 I move to an adjacent grid. If not I try again in a week, this time moving on a 1 or a two. And so on. I'm on a patrol right now that had me in an empty sector for three weeks. I finally got ordered to move...to an even worse location. I think this patrol is gonna be kind of dry.
