Congratulations. This first year newbie is still befuddled by the random effect of Mother Nature. Here in southern Northumberland County (almost on Lake Ontario), I haven't collected anything from my buckets since April 6th. Yet, not that far northeast and northwest of me, people seem to be collecting still. Then, in spite of no freeze-up overnight, ennismaple gets flooded.

There has to be more to this than a relationship to freezing. In ennismaple's case, perhaps it's the vacuum system, but that doesn't explain others who are on buckets like me, and have been harvesting.
