Los Angeles: The Most Diverse City on Earth... Literally

L.A. is the most diverse city on Earth.  How and why did this come to be?  I get into details behind the history of how this happened, as well as dropping some mind blowing facts around it to boot/If you have to do one thing in L.A. this weekend, do this, go see the largest Religious painting in the World!  The story behind this work of art and how it arrived and came to its place of display is perhaps wilder than anything!
