Caddo River tubing
  Our last full day, we decided to take it easy floating down a river in a big tube.  The shuttle
  driver told us to go left just past some cabins.  We went left around an island and eventually 
  noticed we had to paddle a bit to make progress against the wind.  A few minutes later we found out
  why: we were on a dead end!  We walked the tubes back to the turn and went a lot faster.  Evan loved
  the small rapids.
