Yep - sorry for being so cryptic. There's plenty of info on the net and folk can weigh things up and form their own opinions.
Moving to happier things:
I didn't explain Sigurd Olson very well - here's a typical quote:
"I know now as men accept the timeclock of the wilderness, their lives become entirely different. It is one of the great compensations of primitive experience, and when one finally reaches the point where days are governed by daylight and dark, rather than by schedules, where one eats if hungry and sleeps when tired, and becomes completely immersed in the ancient rhythms, then one begins to live." Sig Olson - Reflections of the North Country, 1976.
He is also noted for his death. One winters day he went out in the snow and died suddenly from a heart attack. In his typewriter was a piece of paper. It read 'I'm going on a new adventure, and I'm sure it will be a good one.'
