Replying to JUNE? OR MAMMOTH HELP

I am joining the usc ski club and i dont know whether to buy a 99 dollar june college pass. I am goiing to be staying at mammoth whenever i go up on the weekend and will NOT have a season pass to mammoth. I can get cheap tickets to mammoth about 6 times this year and then the other days i have to drop 70 dollars each time i go for two days. should i buy the june pass? is it worthy? i mean i know its 99 bucks but to a college student thats still a decent chunk of change. Also i would have to take the employee shuttle/hitch a ride from mammoth to june each time i wanted to session june. How is june's park? Does it have good mountain skiing/pow? Thanks.
