I am familiar with the certification for younger boat drivers, it is required in Arkansas as well. Most of what I see is people above the required age group for certification. They just don't care to exercise common courtesy and safety in how close and the speed at which they drive by. It seems to be the same whether on the main lake, in a creek or large pocket. Most of this is just rude I own the water attitude and don't give a s*** about anyone but me.
