Are you allowed to bring a backpack/bookbag? Also about the meet and greet with players do you have to pay for that?

Backpack is allowed and goes through the scanning process. You can meet and greet the players if you arrive early.

great questions. if you arrive early enough all that you ask is possible. entrance to cerfain acti v ities are restricted so walk around the stadium before entering any gate.

Backpack are allowed. Arrive two hours before the first pitch and wait for the players outside of gate 2. You can greet them, take picture and get their autograph

Backpacks allowed. Meet and greets are usually seperate events. You can go to gate 2 and watch the players come into the staidum though. Might get lucky there.
