Maple Jim,
Not sure where you are in Northern Illinois but we are between Rockford & Dixon and typically tap around Valentines day, although last year we did a test tap in late January ant it was running good at 2% so we tapped everything else in. But we were also finished by March 11th because of the warm temps.
