Frank,
Though Bob's youtube presentation is interesting, it is way overkill for my situation. The difference for my situation is I have lots of? tall, skinny evergreen trees. The problem with these trees is they have too few branches at lower heights. The branches they have start at about 50 feet high. But this is good in the sense that the branches and foliage don't get in the way of a slingshot. I have many times used a manual slingshot with fishing line reel attached to place a light fishing weight connected to thin line where I wanted it. It does take time, and patience, and repeated shots to get it right. You also must use a light weight and very thin line. Subsequently, once the weight reaches where you want, you pull up thicker and thicker rope over repeated pullups.?
