except they check your age sometimes... happened to me at killy, dumbass sold me the wrong ticket, also by buying a lift ticket that is like your waiver to be at the mtn, it is the legal aggreement or whatever... i am pretty sure, therefore hiking is illegal, I saw kids get asked to leave killys park when they rode over from pico and we've kicked kids out of our small resort for hiking the hill, it is theft of services...
Buy a lift ticket or get a job as an instructor, have fun giving lessons and ski for free when you arent teaching... good deal
