Biloxi, Mississippi (AP) - The highway along the Mississippi Gulf Coast would be forlorn if not for the casinos, which are having their best year ever. The devastation of Hurricane Katrina has proven to be little more than a temporary setback to the conversion of formerly sleepy beachfront communities into the Las Vegas of the Deep South. Although affordable housing is scarce and businesses have trouble getting insurance coverage to rebuild since the storm, 11 casinos are open in Biloxi, Gulfport, Bay St. Louis and Lakeshore.
