bike tour

Recently went on a bike tour around San Francisco with Chris Carlsson and one of my classes and explored many historical areas around the mission. I was unaware of how many industrially produced foods have their roots in San Francisco! One great anecdote Chris talked about was that before cars were around and before Golden Gate park was anything more than sand dunes, there would be loads and loads of hay being brought into the city for the horses that did all the carrying. The loads and loads of horse manure that would be created from this were used to transform the sand dunes into the glorious green haven we have today!
