As the weather warms up many Northwoods sap farmers start processing their maple syrup

EAGLE RIVER - It's a process that sugar harvester Yukon Jack knows and loves. Jack's been harvesting sap for about 20 years.
He makes 30 to 40 gallons of maple syrup a year.

"I used to hate March and April, and when I started making maple syrup, I can't wait for March and April to come," said Jack.

Jack doesn't tap the trees at the same time each year, but instead waits for the right weather conditions.
