Sorry if this has been covered before, I could not find it while searching.

I will be running some simple lines for the first time this coming season. Do you string them in the fall just before the snow falls for easy walking, or do you do it just before the sap starts to run?

One last question, if you have to do a zig zag with the line, do you just curve it around the outside edge of the tree, or do you have to wrap it around the tree that you are zig zagging around?

Thanks
