I don't know to many hunters that would wear jeans and runners, (sneakers, tennis shoes) while out hunting.
I love the distorted first pic. The guy is probably 10 feet behind the bears head so the bear tends to look bigger than it actually is (typical hunting pic

).
You shoot a bear (black or grizzly) around here without a tag ("the bear was going to kill me") and you'll more than likely end up paying a huge fine and loose your hunting license and firearm to boot. The idea is you don't put yourself in a position that a bear might attack. If, while dressing your deer or moose a bear comes along, you
must leave your kill for the bear or take the chance and try scaring it away. Basically, there is little excuse to shoot a bear unless you have a tag.
