“Sad news about Greg Bear (see FB post from Astrid). Among the many wonderful encounters I had w/ Greg: when I reviewed the Foundation prequel trilogy he wrote w/ Benford and Brin, I said, surprisingly, Bear's novel was the best. He wrote back quickly: "Why are you surprised"?”

Damn. I knew Greg a bit, when I was a teen in San Diablo. He was a regular around Wahrenbrock's, the weird "Hobbit named" SF book shop on EL Cajon, and Jack Davis' Comic Kingdom.
One of our cool HS English teachers had him come by and talk to our class about what being a writer was like.
He was a sweet and generous man.
