I had some first time experiences at this ALA after almost 25 years. I shared a cab with a first time attendee after he Newbery banquet and loved listening to her talk about the wonder of seeing all of the authors and hearing the winners speaking. The Nerdy Book Club was there in force, and for many of them, this was their first ALA as well.
Seeing the conference through the eyes of new folks brings another layer of shine to a conference I already love each and every time I have the chance to attend. Bringing a new vision or a re-vision means using those new eyes even if they are in my old head. It is why talking about books (new and older ones) works. Reading aloud, ditto. Displays, too.
