Correct!  This is probably the drift boat fishermen trying to drive everyone else off the river.  My experience is that the drift guides are mostly from out of state. Their clients are from out of state. The first priority after escapement should be for the residents.  There is no way to get a 10 hp back up to the public landing and launching from the beach may put a vehicle in the ocean with the soft sand and tides. If the drifters want a motor free river then go find one in the wilderness and not on a major highway.  A 10 hp boat is dangerous when the tides are changing.
