I have come across a lake where some guys were alloweded to kill them ? yep , just east of little rock a couple of years ago. i guess you need to aquire a depreadition (sp) permit of some sort ? dont know , but these guys were killing the he#@ out of them.......i asked them about it and they told me they had a permit? must have killed many o dozen if each shot counted...........prolly fired for 2-3 hours nonstop.
