The sugarbush

I was talking to a woman who works at Science Central, another locally-minded person, and she recommends the sugarbush for those who would like to volunteer at a real maple syrup farm (chopping wood, collecting sap, carrying said wood, etc). It sounds like an amazing opportunity for those with older children (Kindergarten, or so). Also, you can purchase maple syrup there as well. By the way, has anyone ever been to the Christmas tree farm on St. Joe Rd.? It is also a maple syrup farm, but everytime I've gone to get information there they are closed. Has anyone been there and if so, could you please give us the information you have?
Here's the link for more info on the sugarbush:
