Put all seasonings in a 10 gallon stainless steel pot (that has a straining basket in it) over a "Louisiana Rig" and bring to a boil. Taste boil for seasoning and correct to your liking.
Put potatoes and artichokes in pot, bring to boil and cook 5 minutes. Add remaining vegetables and sausage. Add blue crab and enough crawfish to fill pot to the top. Cover, bring to boil and then cut off the heat. Let steep 5-10 minutes. The longer it steeps the spicier the boil will become (some people will let it steep 25-30 minutes).
Drain and dump everything out on a table. Have plenty of beer, mineral water and iced tea available!
