Kerry’s presentation on November 2, 2018, covered his experiences during 15 years of attending Burning Man (including his later use of APRS to coordinate his camp). Here’s a PDF of his slides.
Web addresses of all of the web pages that Kerry visited during the presentation are embedded at the bottoms of the appropriate slides.
Update: November 4, 2018: If a few pages of the PDF lack images, then try saving the PDF to disk and opening it from there.
