Yea, I used to use giant J-Plugs....actually everybody did back then, now they are banned....you cast your jplug as far across the river as you can....it floats, so you let it drift until it was lined up for a salmon you could see (polarized glasses) and then reel as fast as you can and you could usually hook up with 20+ salmon in a morning this way. Fighting a 20-40lb jumping salmon hooked through the back is tough. I had a penn saltwater reel with a thick ugly stick and 20lb test line. I remeber the j-plugs slid up the line while the hooks stayed embedded in the salmon. The funniest is when two people from opposite sides of the river would yell "fish-on!" and then you see their line shoot right up in the air as they had snag each others J-Plugs.
I never even used waders. I would go in the water in sneakers and shorts up to my waist lol.
