Steve,
I finished up two weeks ago here in MI. We had a warm spell that just shut the trees off...not that I minded all that much being a lazy ass and all.
Any more, with the kids grown and gone, I do it more to avoid it becoming "the year I quit doin' syrup"...19 years running now.
This year, I boiled around 70 gallons to make 6.5 quarts, which in these parts and with my trees is about par.
Nobody eats pancakes around here anymore so maybe I'll work on a Don Julio and Maple syrup recipe
