I have been saying this for years. If I saw a crawfish or crawdad or whatever they're called crawling across my kitchen floor, I'd stomp that sucker flat. I dang sure wouldn't eat it. Yes, I am Yankee born and Yankee bred. And I NEVER put tabasco sauce on anything, even ham and lima beans.
When I was a little girl, me and my brothers and sisters would go outside after a rain, find crawdad holes and catch them. If we were lucky, we could find them in ditches too.
I use crawdad flies on my fly rod. Once, when fishing in the Meremec, I watched these two guys jigging for them, when I was done and walked back to where the vehicles were parked, they showed me two bucketfuls of them. I forgot what they said they were going to make with them..
