I'm receiving numerous emails regarding autograph opportunities during the upcoming New York week. At this point, the only scheduled autograph opportunity I know of is at the B&N event on Oct. 3.
That doesn't mean there won't be others, this is just all I know at the moment. I would assume there will be post-concert autograph sessions at Radio City, but I don't know that for a fact. It's entirely possible that I won't know until the evening of.
My email time is going to be extremely limited during the next two weeks. While I'll do my best, it would be helpful if you could post your questions on the blog. The excellent and admirable folks around here are quite knowledgeable indeed, and often answer the questions before I'm personally able.
