I have never had a huge fish on my line, but I can remember one time I thought I did. I fought and fought with it to try to pull it in. All my buddies were standing around me thinking it was a big one as well. I would pull in and it would pull back out. When I finally got it reeled in--somehow, I had a branch with my line caught around it and a little fish caught in the branch with the line around it (almost like a net). It was a pretty funny site.
I am sure I could never do that again!
I have never lived that one down.
