I have never attended a Cubs Convention before and was planning on doing so this year.  I was curious as to what current and former players would be there...there is a list on cubs.com for 2008 attendees but they are not guaranteed to be there this year.  Also, my real question pertains to how the autograph and photo sessions work.  Are there usually a lot of good opportunities for autographs, for example does Ryno sign autographs and take photos last year? Any information would be much appreciated.
