stang, see if you can find dehydrated lingiuni alfredo, or something like it. it is usually available in a well stocked sporting goods store with the backpacker's foods.
bring a baggie of chopped scallions, and a container of powdered cayenne along with it.
boil crawfish, remove and reserve water to make the dehydrated linguini with alfredo sauce. seperate the heads (suck 'em if you dare), shell the tails, toss meat into the linguini. mix in chopped scallions, powdered cayenne to taste (should have a good kick), top with grated parm.
