When I float a river to get out a downstream spot, I carry a dry bag with what I may need along the way. This contains a rain coat, change of clothes, basic tools, extra reel with line and leader, a few flies and a five piece Scott Fly Rod. If I am using an inflatable boat I carry a pump and patch kit. On two occasions I have had a friend who needed my Scott five piece rod because they broke their fly rod. This really saved the day and they were able to get good fishing when otherwise it would have been a lost day.
