Yeah, it would be counterproductive to require all the construction workers to undertake a quasi-religious pilgrimage every day in order to reach the worksite. I'm talking about the plan for visitors, which doesn't require any actual heroism; it's based on Joseph Campbell's synthesis of world mythology described at https://en.wikipedia.org/wiki/Hero%27s_journey or http://www.tlu.ee/~rajaleid/montaazh/Hero%27s%20Journey%20Ar.... The best textual source I've found online explaining the specific plan for the obstacles to reaching the Clock is at https://www.edge.org/conversation/the-mountain-and-the-clock, although that was talking about the Nevada site, which hasn't been finished yet, because Jeff has a lot more money than the Foundation does. Stewart Brand gave a TED talk on the subject in 2004; the Monomyth bit starts about 5'30": https://www.ted.com/talks/stewart_brand_on_the_long_now

Cookiemon's comment at https://news.ycombinator.com/item?id=16451497 links to Danny Hillis's lecture at https://soundcloud.com/longnow/progress-on-the-10000-year-cl... which also talks about the Monomyth and theme park design.
