Same thing happened to me . I was trolling Beetles spins on a small lake north of Grand Rapids. Thought I was snagged until it started to move . It just stayed on the bottom . Rod was bent 180 deg. Fought it for about 5 mins and it was gone. Didn't lose the spinner or minnow . Probably a good sized northern . I don't think I could handle a curfew knowing the fish are biting.
