45 or 46 years ago when there was still an opening day for trout season, a friend took me to Clark's Cr. on the Unicoi WMA to fish along with his Dad. Opening day was a tradition with them. It was 12 degrees that morning with snow on the ground. I caught one on a piece of corn, but even when you saw them, you couldn't get them to bite. I started to notice fish laying on their sides in the eddies. What was happening was that the mush ice that was forming along the banks was getting in their gills and causing them to croak out.
I had just watched Robert Redford as Jerimiah Johnson with his "fishing" scene where he was trying to catch them with his bare hands while the Indian on horseback watched him. With that fresh in my mind, I let my inner redneck surface, and went into the creek after them (hipboots). I figured using a net wasn't kosher, but figured bare hands had to be legal. Before the morning was out, I had flipped out our limits. When we checked out at the checking station that afternoon, I think they must of smelled a rat, because we were the only folks there that had more than one or two.
When I started with the agency a few years later and was doing my orientation training, I could have passed a lie detector test that I had never violated a game law. After a couple of days of going through the law book, I figured out that I was a violating sob with more than one miscue. Turns out my J. Johnson imitation was called grabbling, and was illegal for any gamefish.
It was something I tried to remember over the ensuing years that there is a difference between total ignorance and just not caring about a law and doing it anyway.
