Boy Duga,you could stir up a real hornets nest with that statement that the Polar is the 2nd largest, that one has been going on almost as long as the 45 vs 9mm debate, but I do agree a Polar fears nothing, especialy the big boars, will more than likely never see another, but the one I did see up close was impressive, here in the South I would say the most dangerous would be
1.Black bear
2.boar
3.wild dog
