This tweet from Jarrett Barrios credits someone else, but we can’t find an earlier use of the map. (Could be this,) It’s a lovely image that clearly sets up Real Bay Area versus Not the Real Bay Area, with the oddball exception of the WalMart in Mountain View. Other than that, It’s 280 versus 880.
Note: Google Maps only creates ten pins per image. Those little red dots are additional location, location, locations. So yes there are Whole Foods stores, 3 of them, in Marin.
We’d like to know if you can you come up with other easy-to-map measures for RBA versus Not the RBA.
