cheezy - here's some input you should look at regarding the GOM:
my sister-in-law lives in Alabama east of Mobile on Mobile bay, she knows from an extremely reputable source
not to eat any seafood from the gulf. I miss the shrimp myself, I won't eat anything from the GOM any more. She also knows that the local seafood restaurants there are getting money from BP to not advertise or even mention at all that their seafood is not from local waters (a lot of moeny or so I'm told).
