I don't see sleds as a problem on the rivers as much as I see the sled operators as the problem. I hitch rides with friends that have sleds and enjoy the experience of being able to move freely about the river. I also drift the river in a pontoon boat and I hike in some times. Tonight I will be on foot except for the pickup truck I use to get to the trail head. I will use a not so well known dirt road to get that far. Maybe we should ban pickups and start using horses again. I would be in favor of that also if it keeps a lot of the non-locals away from my home waters.
Having said all of the above I see a time when motorized boat traffic will be banned or limited in some way on the Skagit. It won't happen because we as fishermen are complaining but, because of folks like the eagle watchers and perhaps other river user like canoeists and rafters. The main reason will be disturbing the eagles and inconsiderate operators disturbing the canoeists and rafters. I would be in favor of some restrictions or even a ban on motorized boat traffic on the Skagit.
