Kevin,
Your post above is right on! If there is plenty of room for a sled to pass bank anglers or driftboats, the wake is smaller and the time spent in your water less if the sled stays up on plane. When the river gets too narrow, that is the time to slow way down to an idle to slowly pass close by. Bankies and drifters unaware of this take a 'plane by' wrongly as a sign of disrespect, and resort to flipping fingers and rocks. That's often ignorance. Also remember that sleds have to stay up on plane to get thru real shallow water. If you are going to bank fish or driftboat where sleds are appropriate then be aware of these factors and more tolerant. If you can't deal with it, don't fish in sledable areas of rivers. There is plenty of places they can't sled. And I am glad to see that they aren't going to be able to sled up higher on such rivers as the 'Nooch and 'Sop anymore. Those are the areas that sled intolerants can go fish now. Conversely, the sledders have few places to get away from bankies and drifters; so they need to be careful not to fish over bankie's lines and not to low hole other boats by pulling in too close below another boat.
The same applies for bankie's intolerance of driftboaters. You have to be aware they need to pass by. If you have waded out and want them to drift behind you, given enough water, politely wave them to do so. If they have the gall to pull plugs or anchor in the water you are already fishing in then rightfully get on their case! If they don't move then keep casting over their lines until they do - especially if you have 'security' measures in place.
With the amount of fishermen on the rivers in this era, and still growing, we are going to have to learn both basic common sense water etiquette and a better degree of tolerance. The alternative could be sections restricted by user groups. Perhaps in the future fishing by odd/even days according to your birth date? I hope not - unless all my buddies have an even numbered birth date.
