I am having trouble making a decision on this one. My 16 year old daughter wants to go to an all age concert to see Paramore and Fall Out Boy this summer with 2 of her friends. This is at a large outdoor arena with stadium and lawn seating. They would sit in the lawn. If this was at a smaller, indoor concert, where things were more controlled, I wouldn't give it a second thought, but I've seen how nutty some people can get at this location! I am not at all concerned about their behavior, but about the drunken adults instead. At what age did you or will you let your teens go solo to a concert? Thanks!
