the jaw drop begins where the grass on that hillside ends. they've shown it on last year's kamloops episode of drop in, they've also shown josh bender's attempts to drop it in the new world disorder videos - i think 1 & 2 if i remember correctly. it's a 55" overhanging cliff and bender said the landing is like landing on pavement.
i don't think he's hit the drop yet... and i don't think he's going to be trying to hit that drop for long time (if ever) from the sound of what he was sayin' on the that dvd that a2 mentioned. he's attempted it 4 times. after the first attempt he spent the night at a kamloops hospital cause of his injuries. after the next 3 attempts, i think he finally gave up saying that he knows his limits.
personally, i wouldn't drop that unless i had a parachute or unless i was padded up like the michelin man.
