At least this is better for Maple Weekend when one year we had temps in the mid 70's and into the mid eighties. That was a real tough year to keep the evaporator boiling water, had to open every door and window, but the worst part was that most who might have come to visit were at the beach or working on their yards. That year in 4 days (2 weekends) of open houses we only had 3 visitors. Our best year we had a full sugarhouse all 4 days, with lines waiting outside to get in. We enjoyed record sales that year. But we were boiling sap that year too, not water, but when we have an open house we boil slower, use less wood and space the fuelings out, plus we raise the levels in the pans. We do not push it when visitors are there.
