Lil Mike, who used to be over at SFmetblogs but now has his own blog created this map called "Lil Mike’s San Francisco Randomly Revelating Rock n Reeling Pop Cultural History Mystery Tour"
updated September 12, 2012 – LilMike says Google changed the API a couple years ago and the data was lost on this project, so R.I.P
update 2 – it seems the data was saved after all. Also, somewhat related, https://lilmike.me/san-francisco-places-that-are-gone/
ah so that’s what he’s been up to. Spiffy!
