I found the details of this annual event on the following Web site. http://www.wpa.net/~jvaughn/AWT/awt.htm
There is a link on that site for this years event with dates and maps. It makes it nice with the days event and map information so people can plan to see it go by. There are also more pictures on that site of last years event.
