I went to the Maria signing in Pittsburgh on 11-29-13, it was a 2 hr. drive and well worth it. Maria arrived a little early to a relatively small crowd , I was 3rd in line, and she started signing right away.  She was a joy and pleasure to meet, very personable and bubbly, she interacted with everyone there.The signing was well organized and went smoothly, not one complaint.

Here's a couple of pics:
