You're wasting your 2nd choice. Plain and simple. A second choice is only filled if every first choice is filled and there are still tags left over. Therefore, theoretically your second choice could only be filled after you were already issued a tag on your first choice - and they're certainly not going to issue a second tag as well.
2nd choice should be a area with excess tags after primary draw is complete.
True but a second choice doesn't work well if you have a designated hunting party and a specific WMU. Great though if you can move around by yourself or even with a buddy.
