one thing i do on Favera? (sp), usually if we start out all the way by the cars, i stay on the left side, check the alley like ways for people, make the turn at the other end, go into the building, check both ways, especially the one with the open areas, go through there, and go down below, look around, go up the stairs to the barber shop, look through the windows, go down the stairs, go out towards the docks area, go through the construction building, check your corners, go out and make your way back to the start.
after that, i usually stay near the buildings closer to that start point, thats where some good windows are, and that one that connects to a roof
