Walked some of my lines of 3/16 natural gravity,dam squirrels,bears did some damage and a couple trees down,got a few fixed,some to go?Weather not looking good for a while,give us time to get set up.Last year pulled all my 5/16 down and replaced all with 3/16 and WOW does that set up work!! 29" of natural vacuum and does it run!! When is the snow coming to pack the sap in?
