Would there be an age limit at the ffdp and showdown concert?

No I'm 11 and went to see Shinedown, but it is frowned apon.

No it's an all ages show.

Usually not but you have to go onto the website Bridgestone arena website, click the arena policies it's PDF. Any information you need to know is there. They do state that they reserve the right to eject anyone not complying with rules of respect. I have seen them do it so they are very serious.
