I heard this referred to on the radio as a "fifty year drought." Two percent = 1/50 = happening once in fifty years?
Wait a second. I remember being in Berkeley in 1977. Show of hands: who is old enough to remember the color drought charts in public rest rooms -- "Don't flush until the color matches..." -- anybody? But the drought of the 70s was less than 50 years ago. What gives?
No fair. Do over.
