The Legend of Boggy Creek
To see Arkansas's other monster you have to head to the southwest area of the state and visit Fouke Arkansas. This monster is a little more famous than the others . . . he's a film star.
Supposedly, this monster is 7 feet tall and hairy all over. The monster has a characteristic smelly odor and kills chicken, cattle, dogs and livestock but so far it hasn't killed any people. It walks on two feet. It's sort of the southern version of a Sasquatch (aka "bigfoot"). The monster supposedly harassed two families living outside of Fouke in the late 1960s. In 1973, the monster story was made famous in a low budget movie called The Legend of Boogy Creek (Boggy Creek is where the monster is suspected to live).
I've never seen this monster nor have I ventured to Fouke to find it.
If I wanted to see a big 7 foot tall hairy guy who smells bad and bites the head off of chickens, I'd just go visit my uncle Ernie in Bald Knob. It's really not worth traipsing through a creek at 2:00 am in the morning.
However, the cheesy movie, Legend of Boggy Creek, is worth my time. It is very interesting and makes me wonder if this monster might really have existed. I recommend you rent it before you go to find the monster, but get your *MST3k gear ready because this one is a stinkburger. If you can stand the cheesy script, actors and filming, you might learn a bit about out monster.
