Replying to High school ski club advice

I know there's a thread about this already but that was about a club in college and I think the rules would be different in high school. ...

I want to start a ski club and am wondering if amyone has had experience with it. I'm meeting with the principal to talk about it tomorrow. I've already talked to about 10 people who said they would join.

Do I need an advisor from the school to accompany us to the hill and can we take a school bus to the hill? Say we go once a week and leave after school, how would that work? Also, what are other details that need to be worked out?

Plus k for good anwers, and feel free to ask questions I didn't address. Thanks.
