I did it over the fall, winter, spring of 07-08. My shack was actually 8x16 with 8x12 enclosed, and 4x8 porch/firewood storage. It was 2 miles from a paved road, at least 1000 ft higher in elevation than the surrounding area, on a ridge.

No water, but had a creek nearby. No electricity. Had a wood stove, and plenty of insulation.
