I liked the George Mason "golden ticket" event a couple years ago. They randomly put signing tickets in with your regular tickets. People knew in advance whether they would get a signed book or not. It is a factor for a lot of people given the time, expense, and aggravation of travel. Everyone attending with a hope of getting a signed book and then most not getting one can result in a lot of disappointment. If you know in advance whether you are getting a signed copy, then you have all the information beforehand and can decide whether it is worth the effort. I would sort of expect the book store to pull a few signed copies for the employees or local customers. They probably don't get paid a whole lot and it is a nice perk for the time and effort of these events. There are pictures of King signing copies at the PA event. So I wonder if the book store gets a few extras for that very purpose?
Was this the Revival event at George Mason or another? I was at the Revival event and they were stacked up on tables and like the other events passed out randomly and you get one or not. I was unaware of any advance notice or "golden ticket".
I also seen the pics of Stephen signing books before the PA event, and I hope that the staff and fans that helped the staff did receive copies. That would be nice and wouldn't take from the total number offered at the event.
