Silverton Mountain sells this card for $49 (early season price). With a G-Pass you can purchase unguided Silverton tickets fro $39 (during unguided skiing). Silverton says card holders will also "have a special line to buy tickets with," (as if you ever have to stand in line at Silverton.) Here's the real kicker though, The G Pass also gets you 2 free days at Purgatory, 1 free day at A Basin and 1 free day at Monarch.
