4500 XP, Meat Bait
Talk to Antonio after completing the Drowned Hope quest to begin this one. Head outside and use the truck to drive between hydrants. The truck is also useful for killing the bigger enemies like the rams and the thugs. After you have closed all the hydrants, talk to Mother Helen to get you reward. Then you'll be able to talk to Joseph to start the next quest Way of Salvation.
ID Card #039 - To the right of the first hydrant you come to is a shack. The ID is on a table in the shack.
