The titles below don’t always give an accurate sense of what the talk covered. Some talks had summaries of previous ports visits and most talks had notes about what to expect at the next port. Some talks covered questions that were asked of me in a previous talk and I didn’t have time to cover. There is currently a total of 122 talks. Although many of the talks have the same or similar titles, no talk is repeated verbatim, since I add previous and next port information and make improvements to previously given versions of a talk. Not every talk is perfect the first time around!
