Carp tournaments are held regularly here too, I would love to try it some time....If nuttin else it will make you a proficient shooter.
My dad went fishing in Texas a few years ago and while with his guide running 70+ MPH down the lake...they auctually hit one with the boat...Dad said it was quite the sight. They also shoot them with sling shots and such down there too...I find it funny how they do that.
Our commorant population has went down the last few years..dont know if people are shooting them on the sly or what, but the population of them has definately decreased drastically.
