I dont think there has ever been a fish I hooked that I thought was a snag. There have been lots of fish that were difficult to move though.
One fish though did the exact opposite. I was setting up some suckers to fish and drifted out over 50FOW on a lake with sharp drop offs. After I got them out, I proceeded with trolling motor back to break line and started casting.
One of the suckers starting clicking, but never went under. Basically acting like a weed was on sucker. I reeled it in a little and did not feel anything, so I set it back in holder. Started moving again and it started clicking again. I pick up rod and start reeling it in slowly and could feel something was out of place. Felt like sucker was tangled side ways on hook. Float never went under or even moved.
Just kept reeling it in some more until the thing is probably 10 feet from boat and can then see a 48+ musky holding that damn sucker. It looked at me and took off and I set hook hard. Fcught fish for a little while and then it literally jumped over my outboard. I lost it....
