A river trip with your "stuff" unorganized detracts from the experience.  Getting to camp only to find your gear wet is darn near a disaster. You can avoid these problems with planning and the right dry storage to meet your needs. The basics are a bag for the "need during the day," and a larger bag for "things I need in camp."  Or, you can get more organized by breaking your needs down to a clothing bag, a bed bag for sheets, blankets, pillows, or sleeping bags, day hike bag, camera bag, wet gear bag, etc.  You are  rafting, so you have room for more! Now you have more time to find the best fishing spot, hike, or just relax while others are still struggling to find their "stuff."
