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

i think you could be on to something with detour signs, but you would need to put quite a few in a large radious round your safe location. in my opinion you dont want anything like construction works signs or first aid anywhere near you as it could arouse interest, but you might just be able to pull of a toxic dump, unless theres any locals with the groups your trying to keep away
