They are fun.  I think I've been to seven concerts at the least. i've never really been to a Taylor Swift concert, but I've been to others.  It can be outside, inside or a baseball stadium thing or something else.  Most concerts I went to were outside.  I think the only one that was inside was a concert I went to on the 11th.  Some of the concerts that I went to were free for kids, but the concert your going to probably isn't.  You kind of just liisten to music.  Sometimes you sit down, sometimes you stand up, sometimes you run around and play.  I've never been to a Taylor Swift concert so I can't tell you what it's like.  

P.S.  I'm going to go to a concert in October, too!  Their are going to be different bands playing.  I'll name all the ones I knwo about.  Neil Young, John "Cougar" Meloncamp (that name sounds funny), and other people, I forgot.
