No, not the kind where you string up the line between two trees in a park and look like a kooky hippie as you wobble to keep your balance, God forbid you fall nine inches to the soft grass below.
I'm talking extreme slacklining, or highlighning.
That wing suit base jumping video is scary, but kind of cool. This one is just plain insanity.
I don't know about you, but I'm not trying to rely on a piece of rope and a carabiner to break my fall from thousands and thousands of feet in the air as I traverse a peak-to-peak gap JUST so I can tightrope across a nylon strap.
Not worth it.
Oh, by the way...the ones who use the makeshift harness are the ones who are playing it safe.
Check out the video: Screw. That.
One look down, and my brain is blacked out, my pants browned out. At least the base jumpers had a parachute, just in case. These guys just have death wishes.
I am inclined to agree with one of the commentators on this YouTube video, who claims the reason Dean Potter can make it across this terrifying gap without a harness is because his huge balls give him a low center of gravity that aids his balance.
Still...quite possibly the scariest thing I've ever seen someone do.
