Just checked with Mammoth Mountain and if you did not buy a pass for the ski season yet, head to Costco in So.California where there are on sale for $839. Student passes are also available for $399 so with the early season opening you can get your value out of this pass before Thanksgiving!! over 3000 free tickets given out yesterday – with Chair 1, 3 and 23 operating. It did freeze up on the mountain last night so conditions should hold up with the forecast of some cooler weather on the horizon.
