Where are the Endurance Agility Luck and Barter bobble heads in fallout 3

The Endurance bobblehead is in the Deathclaw sanctary. The Deathclaw sanctuary is just northwest of Paradise Falls, if you didn't know it already. When you first walk in, head over to where a brahmin dead body is (it may be glitching and the front half will be stuck in the ground) and right next to it is a small platform. There is the bobblehead.

The Agility bobblehead is at Greener Pastures Disposal. Greener Pastures Disposal is south of Vault 92, and the bobblehead is in the office, next to the Average terminal.

The Luck bobblehead is in Arlington Cemetary. Arlington Cemetary is south of Dupoint Circle and east of Georgetown. Once you get there, find Arlington House, its northwest of Mama Dolce's and on the western side of the map, its on a hill near the center of the cemetary. Once inside, head to the basement, and there will be a shelf that has the bobblehead on it.

For the Barter bobblehead, head east of Smith Casey's Garage and go to Evergreen Mills. This place will be filled with raiders, so be careful. The Mills are divided into 5 interior sections: Evergreen Mills Bazaar, Evergreen Mills Foundry, Guard House, Northern Shack and Southern Shack. You'll want to head to the Bazaar. Once in there, find Smiling Jack, you might as well get the Terrible Shotgun (unique Combat Shotgun) while your here. Just kill him and take it. There are several different ways to do it, but killing him is easiest. But before (or after) you kill him, there's a cave-nook in the room, to the right of Smiling Jack. There's a workbench, jump over it and look on the right-most shelf, and viola. There's your bobblehead!

If you want to know anymore, tell me.
