We would not have been able to do the trip if I hadn't spoken with these people. Most of them have done part of the route before and shared their knowledge of it with me. I picked up many tips on ways to travel, fish, and camp more successfully. It re-enforced the notion that it's important to learn from people more experienced than you when planning an expedition like this. Even if you can't find someone who has done your whole trip, ask them about the part they know. Or, if they tried and were not successful, ask how they would do it differently next time and listen to their suggestions.
