I hesitated to post because there is no 6 star option.. Gran targhee is the best resort I've been to. The liftees are mostly locals and the lines are unsually nonexistant. High speed lifts are great.
And the real reaso why its amaxing, the powder! Most every time I went there (11 times in 2009) there was at least 5", many times 15-20"! even days afterwads you will be able to find powder lines! The terrain is fun and makes the snow more enjoyable
