Flour (Fallout 3)

A rarer item than you think. To find flour, go to Tenpenny Tower and trade with Lydia Montenegro. If you have already had her kicked out of Tenpenny Tower you can find flour by going to Andale, head east to the road. Next head NE along the road past the truck and you will see a diner off in the distance. There is a bag of flour located on the shelf in the diner.

Flour can also be found in:
 * A mailbox in Minefield.
 * A ruined desk on the ground floor of the main building in Roosevelt Academy.
 * A ruined desk in the Children's Wing of Arlington Library. When entering from the lobby, the desk is located in the first room to the left.
 * A metal box in the old computer lab on the second floor of Springvale Elementary. From the stairwell, turn left, go through the concrete barriers, and it is the open door on the right.
 * Gary Staley on Rivet City marketplace has two flours on his corpse.
 * A traveling scavenger had a flour; scavenger encountered at water tower NE of Temple of the Union and due N of Canterbury Commons.
