Fishing Mission Creek: a walking tour

You're invited to attend this FREE survey of how Mission Creek, now chiefly underground (but still flowing), has sustained and given advantage to a succession of humans over the past 1,000 and more years.
We begin with a twenty minute walk through the original Mission site, including the Spanish structure dating back to the 18th century. There is a small charge to enter the Mission museum and grounds; this charge does not go to the walking tour, which is FREE.
Next we step above subterranean Mission Creek, following its course as nearly as possible along sidewalks as a narrative unfolds regarding the Ohlone Indians, the Spanish, the Californios, and the American inhabitants of this evolving habitat.
The walk concludes at the once-upon-a-time edge of a lagoon that provided direct sustenance for the Ohlone, and now provides rent for landlords.
The walk, led by San Francisco social economics historian David Giesen, raises Cain about the privatization of the former marsh cane land now known as San Francisco.
