i know this might not sound important but since i dont wanna leave my ipod in the tent, will they let me take it into the concert? i would leave it at home but i got a long flight ahead of me. the faq says medium sized backpacks are ok but what does a large bag look like(size). its pretty silly to measure my bag. are the people running this all about money. i know water isnt that much money but its pretty ignorant to not let sealed water and food in. is there any way this will change? why cant they sit around and discuss whats practical and whats not. any help would be great. thanks.
