I started a week and a half ago, not so much figuring it would flow but with the deep snow and working on snowshoes I knew it would take me a while to get my 1200 plus taps in. Still have about 200 to finish this weekend but those are 2 small areas and no vac on them so they usualy run a little later anyhow. I got just a tiny bit of flow yesterday maybe 100 gallons total but hopefully flushed out some of the lines atleast. Looks like perfect sap weather this coming week so plan to finish up Saturday and be ready to go!
