Is the Green Day concert all ages?

[Jazmin]

So on april the 4th 2013 Green Day will be playing in MD! So im excited but my dad won't let me go unless im sure it's all ages. Im going with a friend she's 15 and im 14 going to 15. Any answers? Please i'll appreciate them if it's answered quickly.
Md means maryland a state in America for the person who didn't know . I know MD isn't huge. Thanks for your answers i got hope. and they'll be playing in Fairfax, Virginia at the Patriot Center.

Idk. You can look in websites where you get tickets or YouTube some vids and see if its an all ages concert. There was a The Ready Set (sorry if you dont know them) concert like what? 2 weeks ago, I think. And it wasn't an all ages concert. Only for 21+ I saw it on online (instagram,facebook, twitter etc.) lol just saying..but their music was pretty good and not swearing etc. so yeah..depends in the arena and what place it is. So maybe do some research?? Sorry! I never been to a GD concert before. /:

well, most concerts are all ages unless its in a bar. I dont know what MD is, but if its not a bar or club it'll probably be all ages

Yes, Green Day concerts admit all ages...at least for your ages.
