When we skied it during the Goodwill Games, we hiked up skiers right in the trees along the slide's edge. You can probably just whack across it from the resort entrance. I am sure you can get to it from the turn on memorial highway exposed to the resort side of the hill. In the slide giude, its the turn you can see with the stone guard rail. There seems to be a bald spot there that you can hike/ slide down to get into it. We just hiked it from the resort side.
I have pictures of that storm during the Goodwill Games when it was a free for all in there, I will try to upload them. From what I remember, that tight midsection wasn't as bad as it looks from the chair.
I don't post here everyday and seem to piss people off so my voice might not count though.....
