What is the setting of Swamp Thing by Alan Moore?

The time Saga of the Swamp Thing is set in is present day (which, for the title, is the mid 1980s, although very little is present in the contents to "date" the book). Book One takes place in Washington D.C., where Swamp Thing's body has been flown by the evil Sunderland corporation in order to store and conduct tests upon. Books Two through Seven take place in and around the Louisiana bayou, in such small towns as Lacroix, or in Baton Rouge. The setting of the swamp is of course crucial to Swamp Thing's title character, who is composed of swamp material and who cannot stray far from his home in the bayou.
