I remember at GOX 1 the sun was dropping below the horizon as we finished up Gold Bar Rim, by time we got to the highway it was dark.
That's why I think it should be an invite only thing or a rule that you must have run trails at a past GONE before. It's not that I think people should be excluded, but it's not fun holding somebodies hand over every ledge (and there's alot of them on that run).
