Stepping Off of the Grid?

torpor asks: "Has anyone on Slashdot ever stepped off of the grid? I don't just mean long yuppy vacations to pacified islands, but seriously gone from 'tech-dedicated' to 'doing my own thing in the middle of nowhere for a while'. It's that time of year again. I've killed my TV, and I'm finding myself looking for adventure and mayhem in distant quarters. Have any of you ever done this, and returned with interesting stories to tell?"
