If I had to identify the actual moment I began thinking about the ideas that would eventually become the book I’m now trying to finish, it was when I first laid eyes on these drawings, in a flat above the ATM on Belvedere Street in the Upoer Haight, in early 1991. I wrote some about Harper’s “Visions” here: https://speedbird.wordpress.com/2016/02/16/antecedents-of-the-minimum-viable-utopia-cliff-harpers-visions-series/ Enjoy!
