Goog luck in net! dont worry about being a girl, daughter is often only girl goalie but she is fine with it.
also for a full week of goalie camp dont be surprised you will be sore. daughter was sore from her camp, even tho she is staying in shape she hasnt been on ice to work those muscle as often. even 2 weeks later she is in another camp and is sore again. (but this camp is run by olympic female athletes so i can see why shes sore!
) dont worry about age or gender just learn what you need to and have fun.
