I don't know if Theo Sanson's palms were sweating during this world record setting slackline/highline walk, but mine were pouring as I watched as much of this as I could stand. As I've mentioned before, I have a problem with heights, meaning that I'm afraid of them. This is not a record that, even if I was in a record-setting mindset, I would ever try.

In a nutshell, earlier this month, French adventurer Theo Sanson walked nearly 500 meters on a slackline/highline rigged from The Rectory to Castleton Tower in Castle Valley, Utah - likely a new world record. According to those in the know, stringing the slackline/highline between those two points is nearly as impressive as making the walk itself.

Granted, Theo did use a safety leash to keep himself attached to the line, but no parachute in case of complete disaster.
