Would love to go to this one would be my first,what would I expect being a first timer,and what should I bring to be autographed I'm thinking a football,what should I bring?
Expect it to be hot. Hydrate and bring a bottle of water. Season tix holders get in an hour early. Get in as quick as you can if you want a bunch of autographs.
Typically each position group has an individual table and lines form at each. CPJ also signs. The lines for CPJ and QBs are usually the longest but other position groups can stack up as well. Players and coaches will only sign one article for each fan so if you want multiple items signed have a kid or spouse get additional items signed with you. If you want a football signed by the whole team get family members or friends to occupy multiple lines at the same time and jump from one to the other to save time. That's about the only way to get it signed by all imo.
They also have lines for the Rambling Wreck and, I believe, Buzz. Buzz is always there anyway. Cheeeleaders also roam about and will give autographs and take photos with your kids (my girls always seem to enjoy them).
In the past I've bumped into dignitaries such as radio broadcast guys and former players (Joe Ham, etc).
Speaking of kids, expect jump houses and similar activities for them outside the stadium prior to and following fan admittance into the stadium.
That's all I have off the top of my head.
