It's raining cats and dogs because cats and dogs fight = chaos, hence the heavy 'chaos' rain. Snowing cows and chickens because cartoon 'Cow and chicken', they get along...cold and water get along = unity, hence the heavy 'unity' snow. =3
pfft! it's freezing at almost 2am, looking at pink sky - it's a blizzard, snowing cows and chicken...
The big chicken is a Kentucky Fried Chicken restaurant which features a 56 foot tall steel sided structure designed in the appearance of a chicken rising up from the top of the building. A well known landmark just north of Atlanta in Marietta. It was constructed in 1956 and remodeled after storm damage in 1993. The big chicken is used to give directions.
" To get on Highway 85, go 3 miles north and take a right at the big Chicken".
