Dornak wasn't a kid selling lemonade. He was an ecologist collecting pig tails.

The Caldwell County Feral Hog Task Force, a volunteer group Dornak started two years ago, is now at the forefront of the state's patchwork effort to control the wild swine population boom that is hurting farmers, frustrating hunters and poisoning the water in some beloved Central Texas streams and creeks.

Dornak was running the task force's monthly feral hog bounty claim — hunters and trappers get $5 for every tail or receipt for a hog sale they turn in — when he set up his table across the street from the hallowed Texas barbecue hall that is Kreuz Market.

Kreuz and other pork-serving establishments use a different kind of oinker for their short ribs. Domesticated pigs are like Babe: pink, round and thinly furred. Feral hogs are like Chewbacca: dark, muscular and hairy. And they're big. A man in Stephenville caught a 790-pounder on his ranch this year.
