I live about 10 mminutes away from you, just off Jarratt Road and Bill Oliver Road. It's a small world. Now that I know that you live so close, you have no excuse to not come to the annual meets or chapter events. LOL Just kidding, but I sure hope to meet you some time soon and that you consider joining us at the meets and/or chapter events. Perhaps we can fish together some time, like at Calaveras or Braunig.

I Also hope that you join our forum. There is a lot more info on the annual meet and the chapter status then what anybody will find here.

Now it could very well be a musky. But ive been hearing some stuff about the northern snakehead. Apparently these fish are EXTREMLY aggresive. The have a mouth full of teeth and look similar to musky. Well people have been smuggling these fish into america. And heres the scarey part, they can take over and eat an entire lake in only ten years. They lay 1500 eggs and spawn 5 times a year. Thats not good. But these fish can walk on land! They have a seperate lung that allows them to breathe air. They can survive out of water for NINE HOURS!!! Thats pretty amazing. If caught lots of lakes will tell people to kill them. Heres a few pictures.

Very painfull bites

Very dangerous fish.
