One heads up on the Milk Run, Johnson's villiage to Ruby Mountain: For people looking for an float stretch, it starts a bit tough. It starts as a class II+ and then mellows into a class II- run. At high water, it starts as a class III- run. But, if you are using 2 people IK's with a competent person in back, this stretch is no problem, but the people in front will get wet a lot and cold if they don't have good gear on.
Also doing the run from Stone Bridge to Salida is nice because then you can hit Bongo Billy's at the end of the run for hot tea or a beer while others run shuttle. It's a nice ending.
