It depends on the type of zombie as to what to do.
Dawn of the dead slow moving are easy its the 28 days later run fast and shower you with blood type that scare me!
I live half a mile from where i work (i work alone) which is a glass fronted 3 storey building with a glass front and steel shutters. The back entrance is a steel gate 8' high and then a steel door there is are no other ground floor windows. The building is over 200 years old and is made of stone so it's pretty bullet proof
Its in the centre of my town but there are food shops nearby for looting. thats where ill be if mr zombie comes calling.
Weapons over here are not an option so tools will be a cricket bat, battery drill and a pair of running shoes
p.s. i might also insult their personal hygene in the hope that i embarrass them into going home for a shower and not eating me
