Smith Casey's Garage

 is an automotive service garage infested with Mole Rats in Fallout 3. It also houses the entrance to Vault 112 (accessible through the floor gate in the garage's main work-area). Because Vault 112 plays an important role in the main quest, exploring the Vault before completing Scientific Pursuits is not recommended. See the abundance of notes in the Vault 112 article.

is seven squares west of Megaton. An unnamed location marker is added to the Pip-Boy 3000 map during the quest Scientific Pursuits. The Garage can be located before this. But again, entering Vault 112 prematurely is not recommended.

There is a mattress behind the front counter that can be used for sleeping.

There is a military checkpoint on the road north from guarded by a single robot. There is a usable bedroll in the tent as well as several ammo boxes and a Laser Rifle. A squad of two Brotherhood Outcasts and one Outcast Robot tend to appear in this area, where they usually get into a firefight with the military robot guarding the checkpoint. Both the military robot and the Outcasts respawn over time.

Rockopolis

 * Due west of  is Rockopolis, which can otherwise be hard to find.
