Here is a "Top 10 list" of reasons why:
#10 Teton Thai restaurant in Driggs, ID
#9 Never crowded. Located on the quiet western side of the Teton range a.k.a. "Wydaho".
#8 Over 2,000 lift serviced acres providing a wide variety of skiing.
#7 Grand Teton Brewing in Victor ID.
#6 Mary's Nipple - just a short in-bound hike affords fresh tracks consistently.
#5 Great lifties and personalities the likes of Leon Weston a.k.a. "Slim", Carol Geiger & Ignacio Orduno a.k.a. "Nacho".
#4 One of SKI Magazine's "Top 10 ski area's you have never skied".
#3 The Trap Bar...
#2 Incredibly reasonable. You typically can stay and ski for less money than lift tickets alone at most major resorts.
#1 Reliable snow. The Ghee averages over 500+" of snow per year with less than a 5% water content a.k.a. "blower". It has delivered the goods the past 2 years for our crew and it looks like it's going to be a three-peat this year.
