Anchors away - S5-E1
Trivia: During this scene, Carrie states to the other girls, "If you want to do your patriotic duty as New York women, you will come shopping with me right now and throw some much needed money Downtown". According to the commentary, this is possibly the only direct reference to New York City and 9-11 in the entire episode. Downtown NYC was very hurt by the World Trade Towers disaster, and the show thought that Carrie's character would be doing her part, which includes shopping. (00:05:20)
