But some things don't change...even though the Mississippi was down the current was swift...giving us about a 3-4 mph boost. Wings dams (those treacherous rock things the corp of engineers thought were a good idea) were pretty exposed. At least that made it easy to avoid them. And muddy swirling water still made for a rough uneasy ride. Kept us on our toes all day. Still just don't get what Mark Twain thought was so beautiful about this stinky, swirling mess...I can't help but think of all those kids I ruined!
