Above is a picture of the drop in. Your raft can be on top of PVC tubing and then slid down the rails to get it to the water. You start out at the end of a class IV and it's quick moving from there.
Below is a picture of us half way down the white salmon on break. Half way on this river is only about 20 minutes since it takes 45 to get to the pull out. The White Salmon is very cold and very fast, but also very fun.
