Trapper2,
We use approx. 4' drops to buckets, in a former life they were cake frosting pails, 2+ gallon capacity; we dig the snow out at the base of the tree and place the buckets on the ground and then pack snow around them to keep the sap cold and the buckets from tipping over or blowing over due to winds. If little or no snow, then we do the rock trick or lean a heavy branch on the lid to help stabilize the bucket in place. Our woods is flat as a pancake so difficult to use tubing; we push the end of the drops through a matching hole in the bucket lid, no bark, no critters.
