Lol. I just learned a lot about the CCC. I know for a fact that the first one is incorrect, because many of the people ended up going back to their homes. Most of the work the CCC did had to do with the environment. However, the workers did build buildings and bridges. There is a possibility that it may be the third of fourth ones.
