Post Apoc buildings

[nduffy]

So what sort of building materials and buildings would you see PA. I know traditional , log homes, adobe, recycled materials, etc. But what other buildings or styles would the teams see PA, 150 years later? We know many towns would still be in operation, but how would they fair with the potential lack of upkeep or potential lack of skilled people to maintain them... I can see many rural or country mountain folks doing ok, especially those in Appalachia (The hillbillies and mountain folk) The homesteaders and preppers getting by, but what about Joe Schmo? Also I think a skill like primitive engineering would be an added bonus to any team. Any thoughts?
