I live in N. San Diego county. By my imprecise observations, the immediate area has more people of Filipino and Southeast Asian ancestry than the average for San Diego county.
I take walks around my neighborhood, and now I have notice a second yard that always has several filled bottles of water (A clear liquid. I have not opened them) on the lawn. I think in both cases one bottle is near a tree. One set of bottles are Carlo Rossi type wine jugs, another are quart plastic bottles. The bottles do not have tea bags in them, so they’re not brewing sun tea.
My next guess was some sort of Feng Shui (Chinese Geomancery). Anybody know anything?
