I have seen the H2's go up it as well. They get HC'd at the top also and spin their way just over that last lip. I have seen a moderated lifted FJ walk it, and he just cleared that top lip.
The wb on teh H3 for that obstacle is enough of a challenge, than throw in the frame height. The H1's clear it for the most. It seems 1/2 the time the H1's walk it and the other 1/2 they scrape the frame, but still get over.
This place is an absolute riot durring EJS. They have cops out their to dirrect traffic. Last time, I was able to drive down in there in the JK, but the other times, I parked at the end of Hell's and walked down. When you have over 1000 people down there, 1/2 brain dead wheelers that are (insert opinion here), and a huge croud encouraging the drivers...even when they are about to roll, it becomes very entertaining. You don;t want to be at the bottom though.
I bet they shut it down at some point durring EJS.
This obstacle does not look like much of anything from pics and video. However, once you're there looking up/ down at this obstacle, you can see why so many roll on it OR just don;t make it.
I can remember Doug and Steve once saying "you need a broom." get teh loose stuff off and you'd walk it.
