What's this "upper rack" an' "lower rack" stuff? Listen, this is how real country people grill or barbecue or whatever ya wanna call it:

Take a shovel an' dig a little hole. Situate three or four bricks on end around th' perimeter of th' hole. Put some sticks in th' hole an' set 'em on fire. When th' sticks ain't burnin' a whole lot any more, stick a ol' regrigerator shelf or somethin' on top of th' bricks t' keep th' meat outta th' fire. Put th' meat on it an' go play banjo fer a while. Come back an' stick th' meat with a fork ever now an' then. When th' meat don't bleed no more, eat it.
