Back to the Future

This is so cool it gives me chills! First, read John Muir writing about Los Angeles in the late 1870s. It's Chapter 10 - The San Gabriel Valley, on page 79 of Steep Trails by John Muir. On a ten acre property planted with an orange grove generating 20,000 dollars income from the sale  of one year's crop after eighteen years:

 Two thousand dollars per acre per annum from land worth only one hundred dollars.

This is what it looked like in 1915. From http://www.historicmapworks.com/Map/US/19794/Los+Angeles+and+the+San+Gabriel+Mountains+1915/Los+Angeles+and+the+San+Gabriel+Mountains+1915/California/

Now listen to Jesse DuBois on urban farming in Los Angeles.

You get some really weird coincidences on YouTube:
