Last week someone came by and mentioned how much bigger the acorns were this year and said the old story was, the bigger the acorns the harsher the winter will be. I'd never heard that, but we have many more acorns than last year and they are bigger than normal. Actually we had almost no acorns last year and we had the mildest winter I can remember.
Others say size isn't as important as the numbers. The more acorns, the harder the winter.
Unfortunately, this is one of those observations that scientists wave off as being unreliable. But, we have two winters where the acorn theory held up. Last year-no acorns and mild winter. The winter before-loads of acorns and one of the wintery-est years on record.
So. There's that.
