Here's a shot looking down into Parker's Pit, one of our southern Indiana pits just over 100 feet deep. The pit is on private property, and with the consent of the landowner, Nick, Matt L. and I built a VERY simple highline with a reeve system over top of it and lowered the landowner's grandsons into it. We tethered a 1 million candlepower spotlight onto their harness, and they lit up and viewed the pit like very few ever have! Then we used a pulley system to haul them back up. They loved it!
