I don't think you have anything to worry about Tex!

The Tabian Barn is just an official means to know where everyone is living at any given time.

The only real problem I foresee (and that is) if your brother-in-laws are into shady business you could have people arriving on your front door step trying to find them.

That would be my only concern and when considering my useless, worthless, lazy as fuck brother-in-laws!
