Jeff,
Thanks for retrieving Bob's May 18, 2005 article and the original thread.
Tonight I looked through some old paper folders and found the 2005 article, as well as his update of it on April 10, 2006. The update involves a few word changes and pictures he added for red numbered zones 1 through 7. To see the 2006 update online, refer to the Climbing Articles link on the website of the California Mountaineering Club.
