No, I have. Just making a joke that they constantly say that, and it's only now starting to arrive after 4500+ pages. Plus most of ADWD took place in a hot place anyway
I know you said it in jest... But ever since the end of AFFC the north has been stuck in basically one long blizzard. And it started snowing in the riverlands at the end of AFFC as well. So even though the 'official' declaration of winter did not arrive until the end of ADWD - I think you are exaggerating things a wee bit. Winter has certainly arrived.
