Come along on a FREE walking tour of social movement history and theory in San Francisco that proposes that most people welcome the prospect of owning land, and would thrill if their patch of San Francisco real estate racked up steep and sudden inclines in value.

If you were an SF land owner, and you enjoyed sudden and considerable gains in real estate equity, would you protest that good fortune and declare that land values belong to the community? If not, you're in good, which is to say large, company. Including Donald Trump's.

This walking tour will spoil your party, but will also equip you to spoil Trump's and Clinton's (yes, she still wears that patriarchal deferencing last name), and Sanders' party too.

If you're prepared to take a walk on the wildest side of social philosophy hard thinking, peel the sheets and scamper down to the downtownest of the International Youth Hostels this Sunday morning. Your heart and soul will be wide awake by the time we've topped two small climbs of San Francisco's hills.
