A guy I work with lives in Lousiana. I go to a meeting there and he takes me out Nutria hunting. They have 4x4's with huge lightbars. They drive up and down the canals and light up the banks. When the lights hit them they run for the water. Guys in backof the trucks have full auto or semi auto .223's and they spray the bank popping as many as they can. If you miss you have to chug a beer. They are infested and it's legal to kill them anyway you can.
