So, the Debriefing the Dead sidebar in Gatecrashers has someone being questioned who just appeared with a First In team. This someone (Ms. Aster) gives her birthday as Dec. 27 1983. She remembers the war that became the fall, and says she never resleeved. Assuming her story is accurate, that means that in setting there will be Fall Evacuees who remember today. This puts the setting much closer to the present than I had generally thought of it, or perhaps they developed very good longevity treatments very early.
