Mark Schatzker, a travel journalist, has posted two blogs (April 4 and 5) on a hike on the Great Wall with David Spindler on his 80 Days blogsite for Conde Nast Traveler.  In the process, he also recounts some of the knowledge that David has accumulated over years of research on how the Ming Wall worked and whether or not it kept the Mongols at bay.

I also remind readers that I have a few blogs and photos of David and the Wall as well.  See my Great Wall journal.  I promise to add more soon.  We're also nearing completion of a documentary film featuring David hiking on and telling stories about the Great Wall.  If anybody is interested in learning more about this film, please write me at andrew.field@unsw.edu.au.
