Seafood Gumbo

I went to an IT conference in New Orleans many years ago. The Seafood Gumbo at the Hyatt Regency was so good I wrote them when I got back to beg for the recipe. One of the chef's wrote me back with a hand written recipe. I've held on tight to it for almost 20 years now.. putting on zaar so I don't loose it! Sorry for the weird quantities. Adjusted it down from several gallons (10? I forget)
