When I lived in California, I spent summer weekends shark fishing off Avila Pier. On Saturday mornings, the shrimp boat would come in and would sell large prawns for a dollar a pound.
We would bring several ice chests and fill them with prawns. That was good eating.
When I lived in the South (Florida & Louisiana), I fell in love with Gulf shrimp. Butterflied and battered. So yummy!
