A few more details have come to light about Gov. Palin's impending appearance at the Ronald Reagan Library. In addition to what we reported here last week, SVWF spokeswoman Pat Saraceno said attendsnce at the event will be by invitation only, and it will be closed to the media. Documentary filmmaker and radio talk-show host John Ziegler will be the MC. Though a Reagan Library spokeswoman said the event will be held in the library's Air Force One pavilion which is spacious enough to accommodate thousands of people, invitations will only be going out to "several hundred people" who are expected to attend.
