Here’s one from the good folks over at National Parks Traveler, one of my favorite sites. They find some really good googies over at YouTube featuring the crazy sh*t people do at Yosemite. To wit: there are videos of people hang gliding over the valley, a gnarly, stomach-clenching 3000 foot slackline walk (like a tightrope, but, well, somehow different…or maybe it’s just because the guy here has a heavy-accent it just sounds foreign), and a line of people making the hike up Half Dome. As they point out here, what’s scary is not the vertigo-inducing height of Half Dome, or the fact that some of this was shot during a helicopter rescue attempt (about which you see very little), but rather the absurd line of people venturing up the dome. Double yuck.
