When I lived in Louisiana, our house was next to a coulee and we had mudbug houses right in our front lawn. However crawfish was so cheap that we never bothered catching any.
Our annual ACM party was at one student’s uncles place right on the Atchafalaya, where hundreds of pounds were cooked and dumped on tables. Competing against Cajuns made me fast. If you’re ever down that way, there is a place called Richard’s in Abbeville that specialized in boiled crawfish. When we lived in Lafayette they served them on beer trays, but when we went back with our kids they had invented a special tray with a moving divider, so you had more space to put shells as their numbers increased and the uneaten crawfish numbers decreased.
