RE: catchin crawdads?
We catch lots of them. We use some of the hanging baskets that you can hang fruit or potatoes in your kitchen. They come in a package of three at walmart. Take them apart and tie a string to the top of the chains. Tie a piece of chicken or bacon to the bottom of the basket. We drop it into the river off a low water bridge. Tie the baskets to the top of the bridge. When the crawfish start getting on the chicken it will start turning black or dark. When you can' t see the bait anymore pull the baskets up and put your catch in the ice chest.
As far as cooking them, simply buy some crab boil, new potatoes, corn, and sausage. Bring the water to a boil with the crab boil, add lemons, pepper potatoes, corn, and sausage. (They take a little longer to cook). Bring the water back to a boil. Add the crawfish (alive), boil until they are bright red and starting to break open at the tail. Take them out and put them into a styrofoam ice chest. Then you are ready to eat. Bon apetite!
