Would this be a good way to keep people away from you after the SHTF?

I also think its an idea well worth thinking about,.... its not a new idea, it has been done before,... the UK put up false sign post during the war in case of invasion,.. and the troops carried the idea with them to France and did the same for the German convoys.

The trick here is to make the signs believable, maybe pick a place where you know people have helped out before,... say a hospital, just for arguments sake, and have your sign read something like` Roystan Hospital in Fort George offers you food and shelter`,.... if Fort George has done something simular before, then it can make the difference between being believable or not
