Lots of food camouflaged as two homeless guys fighting over a piece of bean. Robbers won't bother for a simple bean.
Camouflage is a good idea, but it wont work good against the zombies. Unless....
Let a zombie bite you. If you can't beat 'em, join 'em.
Zombie repellent/ zombie lure, excellent. That's actually a little like zombie camouflage.
