Video (with sound inserted) of San Francisco 4 Days before the earthquake of 1906. So many historical, sociological, economic, and cultural observations one can glean from this.

Here is a great video that is chocked full of learning possibilities.  It is actual video footage taken 4 days before the 1906 Earthquake that leveled San Francisco.  Of course it did not originally have sound BUT someone edited it and insert sounds that would be typical of the activity taking place.

So cool. Not to be missed!!

You MUST watch to the end when they insert photos of the SAME street in the aftermath of the quake. Chilling.
