Someone who is not willing to pay for a tag, is not likely to be the most ethical of hunters. i.e. - "So I gut shot 'em, I'm not going to waste my time tracking him. I wait for the next one to come by and get that one. <img src=icon_smile_angry.gif border=0 align=middle>"
"It's not the kill, it's the adventure and challenge! <img src=icon_smile_big.gif border=0 align=middle>"
