I was thinking about Reg's big trees, and thinking I'd like to try climbing one. If I did something like that, I'd want to have a line set so I could rappel down if I got too weirded out. How to set the line? Probably out of bigshot range, no? Got me thinking you could maybe fly a line up with a drone. Maybe too much drag for a reasonable machine to carry? Just musing... I'm sure I'll never climb a big tree, and I don't need a drone for the stuff I do, but ya think it would work?
