I've never heard of slacklining, and I don't know why anyone would ever engage in such an activity, but man oh man, this slackline stunt is cool. It's for a Volvo TV spot, and it features a woman by the name of Faith Dickey basically doing a high-wire stunt on a rope strung between two Volvo 18-wheelers. Oh, and those 18-wheelers are moving at 80 mph. And there are very high winds. And OH YEAH, if she doesn't cross in time, she'll smack into a tunnel separating the two moving trucks. So, you know: No pressure. There's a lot of pre-stunt activity, so if you just want to skip straight to the stunt, move ahead to the 1:30 mark then try to keep your jaw closed. Sorry, I should have noted that this was sarcastic, due to the above mentioned reasons. The safety rope seems utterly pointless. Maybe it's for added interest, in case the rope doesn't break away properly when it hits the tunnel and although she made it she gets her leg ripped off. The safety rope might be just a psychological safety blanket, something she wears all the time on other stunts where it would come in handy. Think about how irritating it is when you forget to put your watch on and go to work. Honestly, this would still be impressive if the trucks were going 8 miles per hour. Which, let's be honest, they probably were once they got close to the tunnel. Dustin, you
