Normally my yard does not crunch when I walk in it. So I got curious in November when I started hearing a distinctive crunching sound everywhere I went. I discovered that the oaks in Florida were producing an abundant crop of acorns—up to four times the normal amount, in fact. Acorns were everywhere—covering sidewalks, driveways and parking lots, filling gutters, and rolling around inside the chassis of my car.
I promptly christened 2010 the Year of the Acorn and began investigating why the trees were dropping so many of the hard, brown seeds. Were squirrels sending a distress signal? Could we use the acorns for food? (I imagined acorn-encrusted tilapia and acorn frappuccinos.) Or was this a sign of global warming?
