Put my taps in Sunday the 21st- late, but it's been so cold and there's been no sun. So far 12" maple with full southern exposure has put out 2 1/2 gallons, 28" maple with some southern exposure has put out 4 gallons, and a 22" maple in a shaded spot hasn't put out anything at all. Should be some nice runs ahead 20s at night and sunny days in the 40s/50s.
