I have come to the conclusion it's almost like eating chips.

If there is a huge bag of chips sitting on the table in front of you, you're gonna eat them even if you are full just because they are there. I think some guys think this way when it comes to doe tags (notice I said some, not all). It's almost like an impulse, they can't pass up the chance to get one more tag. Mauser, I'm sure you have a good point too. I also know hunters that feel doe tags are good no matter what wmu they are in.
