You are probably Quite Right! Regarding such a Fill In in places such as New Orleans and Houston. (Bangkok as well comes to mind!). Marshland is Marshland! It's not like we're filling in a "Stone Bottom", Below Sea Level, coastal location. Perhaps variously "In Between" locations can be actually filled in. But places such as New Orleans may very well not be one of them! I *may* so Stand Corrected by you. [color:"black"] [/color] [color:"black"] [/color] [email]hillbilly[/email]
