All wrong.
Anyone that suggests practice before opener is dead wrong. The only true way to learn is a nice spring weekend on the river or on walleye opener. Nothing teaches you faster than that kind of pressure.
P.S. this only applies if you are a decent human being and actually care if you are holding others up.
Nothing worse than the guy waiting in line to unload his boat with all gear in his truck, cover still on boat, etc and waits until its his turn to start getting ready. I can give people a pass for trouble backing, but they dont get a pass for not being prepared.
