We recently took a river rafting trip down the Truckee River in Northern California near Lake Tahoe.  Calling this particular section a Class 1 Rapid would be a bit of an exaggeration, and "hair-raising" is not a description that comes up often.  Typical gear includes sun screen, a well stocked cooler, a hat, squirt guns, sunglasses, and a dog. 

Packing a cooler, by the way, is a finely tuned art...
