A post-apoc version of T1 should be a blast at the table. I still have a hardcopy of The Village of Hommlet module. I just need to decide what system to use: D&D, Cairn, ba5ic, or maybe The Morrow Project...
In Background: "Parts of the world are inhabitable or
too dangerous to visit..." should probably be "Parts of the world are uninhabitable or too dangerous to visit..."
