I may do a few more signs, as well as rooftop gardens, air con units, solar panels, and whatever else I can come up with. I have a lot of these buildings, so I can populate a large-ish town - I just need to apocalypsize them a bit.
I have also gathered together some urban wasteland bits from Khurasan (dumpsters) and Gamecraft Miniatures (jersey barriers, shipping containers) that I can use to clutter up my table:
...as well as two wastelander survivalist camps (also Khurasan). These can be objectives, spawn points, regular old scatter terrain, or whatever I want to make them.
