For the life of me, I can't understand why anyone would want to openly advertise the fact they're out of town. There are all sorts of horror stories out there of people who go on Facebook to post pictures of themselves on vacation, then return home to find out their house has been broken into. And they're actually shocked!!
Why not just put a billboard on the front lawn that reads "Owner is out of town - feel free to pillage!"
Stupidest idea ever, IMHO, and I absolutely wish Delta would quit pissing me off with this. If I want to share my adventures, I'll do it after I get home, thanks.
