This sounds like a "video proof" challenge.
@kyler1945 has thrown down the gauntlet... Who's game!?
Haha, I was hoping I'd tease out some good stuff with that post, and was not disappointed!
There are ways to get up a tree that quickly, safely, and quietly. But it requires practice, repetition, the right gear, and confidence in it.
I will say, the only video so far that's come in under 10 minutes, while showing them actually unpacking the gear for the climb, is Nutterbuster with the crocs and squirrel steps...He was only at about 16' though, so you'd have to tack on an extra minute or so for the last two steps.
I have found that when you factor in all aspects of the walk in, the unpacking of the gear, the climb up/down, crossing branches(more often than not for me), packing up of the gear, and the walk out, they really all are about the same.
So far three methods (not including spurs, I think they probably beat em all) stand above everything else for me - bolts, squirrel steps, one stick/rappel - in that order.
Edit - I should clarify - I'm also leaving out anything preset, sorry rope walkers. Although I still would like to see a video of someone walking up to a tree they've preset, and unpack and get ready to climb SRT or DRT, and get to height. I've made a handful of hunts with rope, but never have timed it, and it has always been slow.
I was not really challenging anyone to go make a video and time themselves. But hell, if it gets folks practicing, I'm all for it!
