Sorry, I'm in Deerfield NH. I too went around and dumped buckets hoping for a freeze tonight and run tomorrow. Just a guess, but a yellow or tan tint to the sap for me always came after a hard rain like last night. I believe it's from rain running down the tree, or dripping off branches. If it aint crystal clear I dump it. Sounds like we have a few more weeks thank goodness. We're having fun over here and dont want it to end LOL!
