if you go the wake board rack route, make sure you get actual ski racks. I think MC makes some. The wakeboard rack ends are to close together and do not fit around your bindings. Unless they have changed them in recent years.
I am taking a guess here but... you could be a one man "team" and "join" the other schools team and travel,pay their fees, and practice with them?? Let me know if you find out any thing I have some friends who might want to do this.
