My footnote to this, forgotten thread is that I carry a copy of the book with me when I travel the USA. I ask pros/assistants/managers to write a wee note in the margin near their course's citation, or somewhere blank if the course went unvisited. It's always a pleasant conversation starter (We remember when he was here or It's too bad that he missed this place)
I forgot to take it with me to the Finger Lakes (NY) region this June, so I wrote a few dedications to my own self, instead.
