Picked up 266 yesterday and boiled it off after boiling off the 535 from thursday. Grade started med and went to light. We are getting great sap temperatures and weather but it won't run due to probably 12+ inches of frost in the ground that was under the 16" of snow on the ground. Snow is mostly gone and until we get rid of the frozen ground, it is going to be a long season. Supposed to get single digits 3 nights in a row next week with bare ground, so it may be end of season before it is gone. Have about 4 more weeks before season is normally over. Sugar content is low too.
