While most sugaring operations used to rely on buckets and spiles, more are upgrading to vacuum tubing systems able to suck more sap from the tree over longer periods.

How much you wanna bet this is gonna be bad in the long-run? I'm predicting that increasing the sap harvest from individual trees is going to damage the trees; and while the effects may not be seen in the next couple years, I bet eventually the trees will start getting sick and start dying because they don't have enough sap.
