First off i am not into this bussiness, i do mowing and landscaping. I enjoy just getting on here am looking at your work. I know this is probably a dumb question ,but when putting lights up in the trees where does the wire run, down the side of the tree? or are they cordless? I have never noticed the wire in any pics. Just thought if you have 3-4 light in a tree, 3-4 wires running down the side of a tree would be ugly and homeowner looking. Also what about mounting the lights, are they on a strap or screwed on. I would think screwing them on would be harmfull to the tree. And last, i am assuming that there is slack left in the line for the growth of the limbs and later reajusting.
