“You might be tempted to say, well that’s a bunch of baloney — global warming,” said Mr. Morse, drilling his first tap holes this season in mid-February, as snow hugged the maples and Vermont braced for a record snowfall. “But the way I feel, we get too much warm.

Ok, so how were real maple syrup crops in Vermont in 2007, 2008, and 2009?
