Are homemade signs allowed in the arena for concerts?

Fold it up in pocket. Dont be too big or ruin it for others

I would not try it unless you are willing to throw it away. Also no pocket knives. Security is very tight!

Yes but they can't be on sticks or poles and can't block the view of anyone

Yes

Yes,no posts or sticks

I hear that it depends sometimes depending on the actual event taking place.

Yes I saw them
