It's Lane Wallace's "No Map. No Guide. No Limits." here.
Lane is well known in the aviation world as a columnist for Flying magazine and author of books on adventure, science, exploration, and so forth. I've known her as a friend over the last decade, mainly through shared flying-and-writing interests. (As noted earlier, not that weird a combination of tastes.) Here's Lane, during some excursion, from her site:
As she has made clear in her writing over the years and in this new site, she has chosen a life of adventure partly in response to personal setbacks and losses. The premise of the site is related to Andrew Sullivan's popular "The View from Your Recession" feature: that many, many people have suddenly seen the "certainties" of their life disappear. The site is meant to discuss the ramifications of and best responses to this fact. And her relatively brief book "Surviving Uncertainty," available as a free .PDF download from the site, talks in detail about how to cope with situations in which you are plunged into the unknown. She uses illustrations from flying and mountain climbing to derive principles that would apply to, say, being laid off or losing a loved one. Worth checking out.
