I know this will be hard for anyone to believe but I used to tube from Isanti to st Francis area and one year me my buddy and brother were riding down and there was a bunch of them traveling north in the river it seemed like our whole trip they were everywhere. We were younger at the time and it made us scared to put our feet in the water all you could see Is red tips and their bars on the sides in the dark murky water when they passed just huge fish no denying what they all were. I have had strange things happen on the rum caught a few huge walleye as well it’s not a great fishing spot but sometimes it does pay off. But the muskie thing only once have I ever seen anything like it. We even tapped some with our paddle just to see if what we were seeing was actually there and it definitely was!
