Oh trust me. I've had tickets the past two years but my schedule sucked. I'm now self-employed and plan to hit it probably twice this year.
My buddies love Mammoth, even after Breck, all Tahoe resorts, etc. They say it's pretty easy to zig zag up and down across the mountain.
I'm not saying it is hard but more to describe the mountain and layout, the map just doesn't do Mammoth justice.
