I have a friend, who is not in band, who actually isn't in the same school zone as the high school we go to AT ALL. (Like a whole different state!) But I would not encourage you to do what she does, which is use another friend's adress. However, just go to the school that you think is best for you. If the one you've been playing in band with is the best, well, you already would have friends since they, as you have said, consider you as 'family.' If you wish to attend the school that all your friends go to, then that's fine also. But keep this little tidbit in mind. Everyone knows you at the school you go to now. Wouldn't it be a great experience to get to know new people when you start high school? The people you grew up with most of your life will know you as you, however much you show YOU instead of you. The people would not know the you your friends know, so you can gain confidence/be more outgoing/be crazy/be whatever and they would not know that they might be seeing the YOU you are. Just think about it before you really decide. And don't forget to bring in the most important people who come up with the final decision: Mom and Dad. Talk to them about it, too. They'll want what's best for you, as well. Just think about the pros and cons and you'll have an answer before you know it!
