I can attest in southern Oregon, that is not a deterent to many road hunters during elk season around here....

many of these clowns will get out and start banging away at elk, without a clue on how far away they may be....and they keep shooting until they are out of ammo or the elk high tailed it into the closest thicket or grove of trees....

to me the limit is only on how far and how well someone can apply the skills they have learned and knowing their equipment.... not some blind luck shot by some road hunting moron...
