I'm about 10,000 ft above sea-level right now, and the wind is howling outside of the window.
At about 11,000 ft, earlier this morning, I was looking out over Yosemite National Park, ski-gloves in hand, scouring the piste for the best coffee locale. Cirrus clouds spiralled overhead. Lizzie, my younger sister, was enjoying the drama of altitude.
This is Mammoth, County Mono, and California's highest ski resort. We arrived on Saturday morning in a rickety old plane from LAX - for the late April snow, the sunshine and the skies.
I miss big skies. Hong Kong's haze is happily forgotten.
