Thinkin' about satellite TV at the cabin. Checked azimuths by running out from shore with GPS on. (My Corps of Engrs lensatic compass is in the kitchen drawer back home). I think I have some shots thru the tree canopy.
Zenith angle is about 30 above horizon in both cases. My options are a bit limited here; I have a couple of shots at the required azimuth angles but I may have to do or have done some tree-trimming. I'm no longer about to climb a tree with a chainsaw in tow but there's one offending limb I think we could drop easily enough with our chainsaw-in-a-can. That's the push-pull manual job with rings on either end, fits in a flat can that might have been made for Kiwi or Coopenhagen. We found it at REI many years ago. It's meant for cutting firewood for backpackers.
The procedure: throw or slingshot a rock or weight over lofty limb, with flexible braided fishline attached. I like dacron. When ya get that right, use line-over-lofty-limb to haul up the toothy chain attached to more substantial lines. Then two operators cooperatively play see-saw with the ropes. A fair amount of profanity accompanies initial attempts but a bit of practice with an able partner smooths that out soon enough. A key initial trick is to get and keep the toothy chain flat-side vertical to get a cut started. Obviously necessary but there's a rope-flicking trick to getting it done when said toothy chain is 40 feet aloft. Fly-casting experience doesn't hurt a bit. Mar and I are pretty good at this. It is flat amazing how fast that sucker cuts once ya get a cut started and a rhythm going. It's thinner than even a Stihl chainsaw chain, it's sharp, and it somehow cuts double-action.
The offending limb would drop into the lake, no prob there. We'd winch it ashore for bucking and conversion to firewood. It would definitely be neighborly to miss Zip's dock in the process... Meanwhile, fishin' is dozen-per-hour good. Bass, not walleyes, Karl. Are we having fun yet, or whut?
