Deer Spit.
I just returned from northern Arizona, where I learned three new things:
1) Never turn your back on a herd of deer - they'll untie your shoes and leave the laces covered in deer spit.
2) If you put your head over the Wupatki Blowhole on a scorching day, be prepared for an icy blast of air from Yaponcha, the wind god.
3) Do not try to keep up with a 5-year-old and an 11-year-old.
They generate 1.21 jigawatts of energy.
Apiece.
