I was driving from TX to MN one yr and got pulled over for speeding in Nebraska. I had a 48 qt cooler with several containers (frozen, covered in ice)
of crappie, flounder, & speckled trout fillets I was taking to share with my family. Cop asked what was in there, I told him. He asked if I had left a 1" square patch of skin on each fillet. No. He didnt ticket me for it but could have. I think its a pretty much nation-wide law and just something to know.
I have not and probably never will amend how I transfer fish because of it but sure nuff if I didnt say anything yur Dad will get popped for it and I will think why didnt I mention it.
