San Francisco Sourdough

Aside from the fact that the wild yeasts and bacteria that populate the city of San Francisco can be found elsewhere, I really think that the sourdough breads from San Francisco do have a distinctive taste. The breads I make far from San Francisco really don't taste very much like the breads from the bay area even though the starter I use may be similar.
A curious thing about starter (at least mine) is that it seems to know if I'm away on a trip (just like a pet), and I am punished for not giving it the close attention it is used to. Upon returning home, I find my starter balky and resists getting motivated again.
I know it's crazy, but do the yeast and bacteria have some type of awareness that we fail to comprehend.
