APRIL 24, 2026
Greetings!
Due to a severe cold and a number of family matters (minor surgery, trips in and out of town, sending my son off to Chicago), I have gotten behind in managing this site. I hope to remedy that very soon. Unfortunately I must cancel my talk on April 25, as this cold is not releasing its hold.
More to come, and thanks for your patience!
Mark
