[How autobiographical is Sandy Blair from The Armageddon Rag?]
There are autobiograhpical elements in many of my characters. After all, the only person you ever really truly know is yourself, so to make a character come alive, you need to delve inside.
That being said, I probably used more of the actual facts of my life in making Sandy Blair than any other character except Tom Tudbury of WILD CARDS. Personality wise, however, I suspect I have more of Tom in me than I do of Sandy.
