A lot of people do add things to their shrimp, crab, and/or crawfish boils down here. Potatoes (especially half dollar size, red potatoes) are most common and corn on the cob; however, hot dogs, smoked sausage, artichokes, garlic, onions, and many other more interesting (we have friends who boil squid in the seasoned water along with their shellfish) add-ins make the boils more fun. I like all-beef hot dogs (Hebrew National), but many people use the really cheap, red weinies.
My husband and father-in-law (my in-laws live in Bloomington and were down here for Easter vacation) went out with a friend who owns a crawfish pond in Kaplan, Louisiana, and pulled the traps themselves. The guys said the pond was way in the back and the traps hadn't been pulled for a while. Consequently, the crawfish were huge; some the size of small rock lobsters. Even the claw meat was substantial.
Thanks for responding. I love seafood. We lived in California for seven years, and just moved back to Louisiana last summer. It's good to be home (I'm originally from New Orleans), and we are loving the food.
