I've got a three day prairie river trip planned for September. My buddy Patrick will fly over from Australia.
I got a whole frozen pork skin from a local butchering operation West of town. Will cut it up into strips and mount them on a snell, with swivel up front, like a Carolina or maybe Texas worm rig. Then put them in a vacuum canister with a bottle of salmon egg juice and suck the air out so the salmon egg juice marinates deeply into the soft wet pork skin. Let it sit for a few days--still in the vacuum canister--and then re-freeze it, so I have sandwich bags with 2 or 3 pork/worm rigs per bag.
Why?
Channel catfish. On the fly rod. I'll fish them with a big 1/4" inch Tungsten bead in front of the rig, with a heavy but loooong leader, so I can get depth when I need it. I've done this before. I love it. I caught one 25" inches last time and it almost broke my six weight fly rod. I'll use a bigger 8wt bonefish rod this time around. My buddy Patrick hooked and lost one so big it towed the boat for a while.

Will they also bite dry flies? Probably not this one:
.........maybe a mouse pattern?
