Unfortunately isn’t a matter of whether or not you should be able to go or not, but legality issues. One cannot sign a legal contract, buy legal drugs (cigarettes), and be tried as an adult in a court of law. The latter two could be the reasons that it is an 18 plus event. I am 18 and I felt the same way when I was 17 but it is just the law. 18 is also the age of adulthood in some states. This could also be part of it. So, yeah, I think access should be based on a maturity level, but unfortunately it is not.
