"Niantic stocked San Fransisco and left us all with Pidgeys"

#PokemonGO: After a trip to SF, I've picked up on a few things about the way pokemon spawn in different cities. I know Google search data correlates to spawn points, which explains why my local truck stop has 10 pokemon at all times without a lure in sight, but this completely contradicts the concentrations I've seen in San Fransisco. For instance, The Presidio had 100% of the time at least 8 Bulbasaur, just a short walk away in Fort Mason there's always 5 or so Squirtle and 2 Pikachus. Take a short drive down to Niantics building and theres a Charmander hot spot. This doesn't end with the starter pokemon, I've caught several Dragonites, Vaporeon, Arcanine, even 2 Raichu. Any pokemon you want, SF has a handful spawned at any moment. I expected SF to be a popular city but the pokemon were overwhelming compared to any other city I've looked at. When Pokevision was working you could really see how nuts it was. The only comparable city was NYC which has a population 8x larger. Other larger cities, LA, Tokyo, HK for instance, has 1/10 the pokemon of SF. I think the algorithm determining spawn points from google data can't be the same that's determining these hot spot nests. I think it's fair to say that some of the busiest spots of several larger cities should have more Google searches than a small park in San Fransisco. It seems as if these spots were hand picked, or stocked like a pond. Here's an example of what I'm talking about http://ift.tt/2aRJc8T'm interested to see what everyone thinks about it.Edit: Here's one more for you guys from what I now call, Pikachu Park. http://ift.tt/2arYW66 via /r/pokemongo http://ift.tt/2b5lbP5
