Several days to prepare? Several days? You think that is enough time? I mean, do you have any idea what you are talking about?
Seriously -- have you ever been to a big city? Presumably you've been to Atlanta. When you were there, did you notice the density of the buildings there? The sheer magnitude of the geography that has been built up by decades of construction? Now, think about that, and multiply by 3 because LA is that much bigger.
And then ponder to yourself, "what would be required to fireproof the 8000 square miles that comprises the Atlanta metro area, with the trillions of tons of building materials and the vast quantities of vegetation that I won't even try to estimate"? Would the answer be "several days" or "several years"? And then triple the estimate.
Several days. My God. Even Trump isn't that stupid.
