San Diego chapter honcho Tom Del Hotal has herein made available a ton of his inimitable presentations and handouts.  Enjoy.  And thank you, Tom!

NB For some reason, these links are not currently working in Firefox. They seem to work fine in Edge and Chrome. Be aware that some of the pdfs are huge and will take a long time to load.

If you prefer, you can easily see all of them and even download them here.
