We just spent three days whitewater rafting in Glacier National Park, Montana. It was great fun for many reasons, but one thing that really struck me is how rare it is to completely unplug these days. No cell phone, no email, no TiVo, no electricity. Not even an iPod. Just a raft, a tent, and an open fire for cooking. And I’d venture to guess that of the 15 other people on our trip besides the two of us, not a single one even knows what a blog is, let alone writes one. In many ways, those three days of being unplugged were as refreshing as two weeks on many other vacations.
