I took Friday off work and attended three out of four days of the big SCBWI conference here in LA. (SCBWI = Society of Children's Book Writers and Illustrators, an international organization I belong to.) I went last year for the first time, and it was fantastic.
This year was also wonderful, although a bit less useful to me overall than last year. I think I'm sort of getting then hang of this stuff, and am no longer quite a newbie! Weirdness.
I'll report in more detail as my brains de-scramble, but if you are at all interested in writing for kids and have the time and money, I urge you to attend one of these conferences. They are valuable for their huge infusion of inspiration (I cried during two, count em, TWO speeches) and practical knowledge. For me, the best parts were meeting some nice fellow writers and getting to know more about a couple of interesting agents that did workshops there. Attending the conference automatically gives you more of an "in" with agents and editors who teach there. It's no guarantee they'll take you on, but it sure can't hurt!
