This is New: BASE Jumping Off of a Slip and Slide (WATCH)
Devin Graham and his friends are unique individuals. If you thought BASE jumping off our Perrine Bridge was extreme, wait until you see Devin's video of his friends doing it off of a Slip and Slide situated on a 500 foot cliff.
Here's Devin's description from his quite lively YouTube channel:
INSANE Slip and Slide off a 500 FOOT CLIFF!!! World's Tallest Slip and Slide!
You would not believe the preparation and setup that went into this stunt, but you can watch it.
