Absolutely agree with you about Ron Smith’s Pan-Andes stuff in The Sugar Beat, Kowalsky, but remembering that yarn led me also to remember another mega-locale (with a Ron Smith connection no less) that could be added to your geographic labours should you be planning to cram a few more places in.*
Puerto Nova - perhaps a bit obscuro but mentioned a couple of times in Judge Dredd, though I can’t recall ever having actually seen it. A wild stab in the rad-mists would place it in Puerto Rico, but I’m just guessing here. Unlike the Pan-Andes Conurb, I can’t remember it exporting much in the way of ilicit crops but it did export some wonderful Ron Smith pyrokinetic mayhem back in the day. I’m away from The Library at the moment so I can’t recount the progs involved right now should you require them.
*Bloody dandy work, man. I think between yourself and John Caliber, all you’ll soon leave for the rest of us to compile will be the list of MC1 Adverts and “Holding Posts I Have Known And Soiled.” Fabulous.
