Copperheads

This guy's yard is chockablock with 'em

LITTLE ROCK (AP) - It happens every year: large numbers of copperheads gather and move in unison to dens for hibernation. But it happens in October, not July or August. Now the common event has become an uncommon and inexplicable one.
``I know for a fact that all these snakes didn't just wake up one day and do this,'' said Chuck Miller, whose Marion County yard has been overrun with the pit vipers. ``Something's making them do it. They know something we don't know. There's got to be something more to this.''
Nearly 100 of the snakes are using a cedar tree as a sort of meeting place, and neither Miller, an outdoorsman and former snake owner, nor scientists who have traveled to the rural north central Arkansas site to study the phenomenon, know why.
