I will admit it has been awhile since I have been to warped tour, but I would say if this is going to be your 1st concert with her be prepared, its got more of a carnial theme then a concert. With the amount of bands ti can get kinda of hectic. If you are planinng getting autographs, keep track of time on when you go to tents cause you can miss windows pretty easily. Don not wear flip flops and depending on the date drink a ton of water. Bring $$ cause you usually cant bring any in. Basically a band will play a set (4-7 songs) then crowd desperses , next band comes up crowd comes back. With a 14 yr old dont go right up to stage cause you will want to avoid mosh pit. There prob will be alcohol (they have those 21 and up wear a baclet) sometimes they have desg smoking areas at other venues not, call teh ampitheatre to find out their rules. For a 1st time concrt goer it could be a lot to take in, find out the time the bands she really wants to see go on and time you arrival appr otherwise you could be there ALL day. It is a blast though and one she will never forget, you will ahve fun as well as long as you know what your in for, have a great time :) If you have any spec ?s feel free to mess me.
