You'll have to forgive how much of my attention is given to Becca this week, as she wends her way across the southwest toward the south. Yesterday she achieved the Grand Canyon; today, after a break for a meteor site, she's heading for Alamagordo, the better to see White Sands (inspired by klages's Green Glass Sea and White Sands, Red Menace).
You will note that my daughter is humbled by the vastness of the Grand Canyon.
