If you’re a follower of this weblog, you may have already read the comment from follower Greg deGiere:
I just learned about the Berkeley Historical Plaque Project and want to urge someone to submit the Stewart house (which I found once through a street directory in the Berkeley Public Library), which is where I assume George wrote. As a student of political science, it has special meaning for me because, as I understand it, it was the model for Ish’s house and living room is where the state was created, so to me it’s something like Independence Hall.
I replied, suggesting that if he wants to work on the nomination, we’ll help as we can. The idea is a good one, and appropriate.
The house on San Luis Road is the model for Ish’s home in Earth Abides. He disguises it by renaming the road San Lupo Drive, but the physical characteristics of the house and the neighborhood are very close to the real house, as it was in the days of Ish.
It’s been changed quite a bit now, but his idea is something we should consider. Stay tuned.
Good idea, Greg.
the EARTH ABIDES project 
Without doubt, Stewarts house, in both fact and fiction, should be identified as ther site where a great man lived. My short account (6,500 words) of my visit to Berkeley in the mid 1980’s can be published on this blog if there is interest.
Yes, Steve, we can publish that. I may edit it, but would get your ok for the edits.
