On Guam, you have to have a propane tank. They don’t install gas lines because of the earthquakes.
For a small isolated place, with limited disaster resources, this makes a great deal of sense.
I can see the same argument being made in Eww Yuck.
It would have been a good idea before any gas lines were put in place.
That decision (for SF) was made in 1930!
