Footlockers:
A number of areas in the world have footlockers in them. These areas are in place for rogues to visit to increase their lock picking skills. The contents of these footlockers are only token amounts of treasure, but they should allow for a more interesting experience while increasing lock picking skill. The difficulty of the locks in the area corresponds to the level of the zone, so if your lock picking skill is around 100, you would go to Durnholde Keep in Hillsbrad. But if your skill is 250, you might head to Tyr's Hand in Eastern Plaguelands.
