Sweet and sappy. It's maple syrup making season. The warm winter is bound to have an impact.

RACINE, Wis. (CBS 58) -- Racine's River Bend Nature Center is busy collecting its sap from about 130 maple trees. The hope is to collect more than 500 gallons of sap. In general, 40 gallons of sap will get you a gallon of maple syrup. One of the naturalists on site says it's hard to know exactly how our warm winter will affect the overall production. But the warmer weather gets the sap flowing faster, collecting into 3-gallon bags. If not tended to soon enough, the contents could spoil before reaching the evaporator where the sap is "boiled down" to become syrup. This syrup, by the way, will be served at four pancake breakfasts the first four Sundays in March at the center.
