In Andale, (Near the Nuka Cola factory). You arrive there and Old Man Harris (?) tells you to leave while you can. I talked to everyone and my lockpick skill isn't high enough. I know it isn't even a quest but does anyone know the story behind it? Thanks!
There should be a key lying around somewhere in one of the houses, so that you can access the shack/basemant without lockpicking. More fun finding this out yourself.
