Things to do before a concert?

I'm 12 and I'm going to a concert next year on July 8th and all my cousins (I'm the youngest) have a tradition that in the year running up to the concert you need to make a list of 15-20 things to do and complete them before the concert or you have to pay 25% of the next concert ticket price and including me there are 13 of us.
Really don't want to pay too much for the tickets next time because I'm saving up for an iPhone.

Breathe, Touch a wall with an apple, all that stands for "Things to do". Except if you made restrictions to only do things more dangerous than backflipping with a pogostick over grand canyon while singing the national anthem.

-Sing a song by the person/band you're going to see

Repeat 15 times.

  • What should I bring to my one direction concert? I'm planning on bringing my iPhone and digital camera in a very small side bag. Is that a good idea? And how much money should I bring. Please only serious answers. Don't comment if you just want to diss one direction.
  • What if i can't print my concert tickets? I'm not able to print concert tickets for warp tour, but i have the file on my iphone, it clearly shows my tickets and the barcode, will i be able to let them scan that/would they?
  • What cameras are best for concert photography? I love going to concerts but my iphone camera is just not too good at taking photos at concerts. Is there any cheapish cameras that are good at taking photos and or videos at concerts?
  • I found this iphone at a concert? I found a. IPhone at a concert like a about a year ago if I take it to Apple will they take it from me because it's like stolen? Or can I say I bought it off a friend at school or something. Can they take it away?
