2 is nothing, Lesley!! But since you're way past your 1L/tap, I wouldn't sweat it.
Although we all hate to do it until the last possible moment, it *is* ok to pull taps when we want to be done with sugaring for the season - even if the sap is still good.
You've had a great run. I'd like to see a picture of the trees that gave you this much syrup! :D
