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

[Highlander]

You would have to be very suttle with this idea, people are not daft,..and deperate people are more likly to take more risks that they would normaly,...so signs of danger, i.e contamination of some sort might not work,... it would not be hard to vision some desperate folk seeing a sign of Anthrax and trying to pass with hankachiefs against their mouths, if they did, they would soon see the trick,.....and besides if you went along that road with dead animals and the birds were still flying around and singing their hearts out, it would look a bit suss

Instead of a `warning` sign, it would be a much better idea to give a `hopefull sign`,... you give people hope and they will follow,... give people a warning, and they are more likely to try it out and take a risk
