If the trail I was on this past weekend is any indication, there's absolutely no risk of ultralight being to "mainstream".

Just because a book is available to the masses, doesn't mean they'll actually read it after all...they're probably prefer to wait for the movie <img src="/forums/images/graemlins/wink.gif" alt="" /> <img src="/forums/images/graemlins/grin.gif" alt="" />
