Hey Floater,
For a change of pace, you might try the John Day river in Oregon. Mid spring when flows are in the 2500, to 5000 cfs area have been great times for my friends and I. I know its not our first choice, but the smallmouth are generally large and plentiful. There are many choices for multi day drifts. Service Creek/Clarno, or Clarno/Cottonwood are two excellent and very relaxing sections.
Just a thought...
