[pct-l] Jacket questions?

[Diane Soini of Santa Barbara Hikes]

Somebody should post this every day until the start of the next thru- 
hiking season:

The desert is cold! You need jackets, sleeping bags, rain gear,  
possibly some snow gear, the works! It is cold.

So many people believe it's all desert, all tumbleweeds and cactus  
from Mexico to Kennedy Meadows. Hardly the case. Some people believe  
that if it is desert, it's hot. There's no humidity so as hot as it  
might get during the day it can get equally/inversely as cold at  
night. It can get cold during the day, too. I froze under the  
Cottonwood bridge on Aqueduct day.
