I’ll be in an untethered state until June 10 floating, and sometimes cataracting, down the Colorado River through the Grand Canyon.  No electricity, no cell towers, actually, no toilets but that’s a different matter.  Five oar-boats, two kayaks, plenty of polar-tech (it’s still 48 at the Canyon rim,) 21 days of food packed into enormous coolers — don’t open this one until day 17!! When I surface I ought to have plenty of good photos –if the solar chargers keep the batteries going– and some good stories to tell….
