Unmarked cities on the Fallout 1 World Map.

I was always curious about this and Fallout Bible never mentions those. Any Developer info about them? The one near Lost Hills bunker might be the original location of Necropolis before it was moved to spread the locations along the map, as Bakersfield is roughly around that area.

I never thought of those as previous enter-able locations, I figured it was just generic Blown Up Pre-War Towns...

Y'know, just something to make the wasteland more than just endless desert, and add a bit of realism

Another possibility is it could potentially be a throwback to Wasteland -- although I haven't held the maps up side by side. Just a thought.

Either way, good question!
