The other day I had three lines get cut. And I say cut because three diferent times I had what felt and fought like real big fish on and just before I got them to the boat the lines were cut. It was 14 lb cajun red and the knots didn't pull out. They weren't frayed or jagged or burnt looking. They just looked like smooth cuts probably a few inces above the hook. I've never caught a gar, so I don't know if they can do this or not. If it wasn't gar then I just don't know.
