You can make sour-dough bread anywhere in the world but it never tastes
quite as well as that made in San Francisco. I think it is a special
sub-species of yeast that reverts to the local varieties even if you
bring some from San Francisco. Nonetheless, making your own sourdough
"starter" is quite easy.
