lol... crawfish aren't bad, they just require too much work for the little bit of meat you get.
I should have you come to my house. It still flips me out because I live in the mountains of WV and there are no significant bodies of water nearby... but the water table in my yard is very high. Whenever it rains and the yard floods, tons of crawfish come out of the ground. During Spring-Fall, you can see their burrows in the mud all over the place.
