2 springs ago I was fishing in my buddy Jeb's boat on Beaver, I had just caught a keeper sized walleye on a jerk bait, checked my line, it was OK, made another cast, twitch, twitch, paused the bait back to the boat, and gave it one final pause right at the boat where I could see the bait. A big fish appears out of nowhere, all I could see was the head, and the jerk bait disappears as the fish inhales it. Lift the rod, line seperates with little pressure just like it had been cut. I didn't get a good look at the fish, but I'm convinced it was a big walleye.
Every once in a while, especially on TR, I'll get a bite, lift the rod and the line seperates, I'm convinced it is not because of frayed line or bad knots, it's cut. I blame it on walleye, but it could be something else I suppose. Could be gar, but I've had it happen when the water is cold and the gar are not active.
