Quoting Cody G
nice build. you should have a manhole that zombies can come out of, and if you have any of those string things attatched to the studs (look at the grapple gun in my diorama with the red tower), then those might look better than chains for the power lines.
Thanks for the suggestions, but there actually is a manhole built into the road, go and look at the main pic! Definentially need to change the powerlines, thanks!
