jiminy is a great place for high school ski clubs, its small and pretty easy so you can bring that into account with trying to grab interest from students. how close is it to your school?
here are a few things to think about: distance, cost, what will they get out of it, where will they get equipment if they dont ski?
building a flyer is the easy part. you need to have a pitch.. for example, organize a bus for everyone in the ski club to get a ride to the dew tour at mt snow. even people who dont ski want to go to an event of that stature, so if htey join the club they will get to shred jiminy AND check out the event.
so where's my dutchie at?
make sure to put on the flyer that anyone who doesnt own equipment can rent it at the mountain http://www.jiminypeak.com/page.php?PageID=1336&PageName=Rentals
here are some good graphics to put on it http://www.istockphoto.com/file_thumbview_approve/5315243/2/istockphoto_5315243-freestyle-skier-silhouettes.jpg
