Climate change? Global warming? Just mom nature's cyclic fits?
Who knows what the answer is, but rainfall at Mammoth Cave National Park this year has been so low -- 10 inches below normal since the start of the year -- that the Green River is too low for the Green River Ferry and Houchins Ferry to operate.
Whenever enough rain arrives the ferries will set sail. For information, call the park at 270-758-2166.
