The endurance bobblehead is among the most difficult to acquire as it is located in the Deathclaw Sanctuary. The republic of Dave is located in the far northeastern corner of the map, east of Old Olney. The perception bobblehead can be found in the museum of Dave in the Republic of Dave, on a bookshelf. The best way to get in without being lucky or investing skill points in lockpicking is to pickpocket the key off of Lucas himself. Generally, the house has a level 50 lock on it and it is very rarely unlocked. To find it you must head upstairs into the room to the left and take it off of the desk. The strength bobblehead can be found in megaton in Lucas Simms' house which is directly to the right of the entrance. Warning: The Strength Bobblehead is one of the few bobbleheads that can become permanently unobtainable this one becomes unobtainable on the condition that you completed the quest 'Power of Atom' in favor of Mister Burke
