I summon this thread to arise from the grave!
Ahem.
While going through some of my old files, I found my copy of DriveThruRPG's
guide to Twilight: 2000 v1.0 products. Page 24 provides a suggested map for a geographic (and thus implicitly chronological) progression of CONUS adventures, including both modules and
Challenge articles.
I'd attach it here (it's free promo material) but the upload function choked out. Still, it is free. Downloading it does require you to register as a DriveThru customer, but that's not really an onerous burden.
